Nbins is the total number of bins; Nvalues is the -number of input values specified. Each processor loops over its -atoms, tallying its values to the appropriate bin. Then the entire -array is summed across all processors. This means that using a large -number of bins (easy to do for 2d or 3d bins) will incur an overhead -in memory and computational cost (summing across processors), so be -careful to use reasonable numbers of bins. - -:line - -The {Nevery}, {Nrepeat}, and {Nfreq} arguments specify on what -timesteps the input values will be used to bin them and contribute to -the average. The final averaged quantities are generated on timesteps -that are a multiples of {Nfreq}. The average is over {Nrepeat} -quantities, computed in the preceding portion of the simulation every -{Nevery} timesteps. {Nfreq} must be a multiple of {Nevery} and -{Nevery} must be non-zero even if {Nrepeat} is 1. Also, the timesteps -contributing to the average value cannot overlap, -i.e. Nrepeat*Nevery can not exceed Nfreq. - -For example, if Nevery=2, Nrepeat=6, and Nfreq=100, then values on -timesteps 90,92,94,96,98,100 will be used to compute the final average -on timestep 100. Similarly for timesteps 190,192,194,196,198,200 on -timestep 200, etc. If Nrepeat=1 and Nfreq = 100, then no time -averaging is done; values are simply generated on timesteps -100,200,etc. - -:line - -Each per-atom property is also averaged over atoms in each bin. The -way the averaging is one across the {Nrepeat} timesteps to produce -output on the {Nfreq} timesteps, and across multiple {Nfreq} outputs, -is determined by the {norm} and {av} keyword settings, as discussed -below. - -Bins can be 1d layers or slabs, 2d pencils, or 3d boxes. This depends -on how many times (1, 2, or 3) the {dim}, {origin}, and {delta} -settings are specified in the fix ave/spatial command. For 2d or 3d -bins, there is no restriction on specifying dim = x before dim = y, or -dim = y before dim = z. Bins in a particular {dim} have a bin size in -that dimension given by {delta}. Every Nfreq steps, when averaging is -being performed and the per-atom property is calculated for the first -time, the number of bins and the bin sizes and boundaries are -computed. Thus if the simulation box changes size during a -simulation, the number of bins and their boundaries may also change. -In each dimension, bins are defined relative to a specified {origin}, -which may be the lower/upper edge of the simulation box in that -dimension, or its center point, or a specified coordinate value. -Starting at the origin, sufficient bins are created in both directions -to completely span the bin extent in that dimension. By default the -bin extent is the entire simulation box. - -The {bound} keyword can be used one or more times to limit the extent -of bin coverage in specified dimensions, i.e. to only bin a portion of -the box. If the {lo} setting is {lower} or the {hi} setting is -{upper}, the bin extent in that direction extends to the box boundary. -If a numeric value is used for {lo} and/or {hi}, then the bin extent -in the {lo} or {hi} direction extends only to that value, which is -assumed to be inside (or at least near) the simulation box boundaries, -though LAMMPS does not check for this. - -On each sampling timestep, each atom is mapped to the bin it currently -belongs to, based on its current position. Note that the group-ID and -region keyword can exclude specific atoms from this operation, as -discussed above. Note that between reneighboring timesteps, atoms can -move outside the current simulation box. If the box is periodic (in -that dimension) the atom is remapping into the periodic box for -purposes of binning. If the box in not periodic, the atom may have -moved outside the bounds of any bin. - -The {discard} keyword determines what is done with any atom which is -outside the bounds of any bin. If {discard} is set to {yes}, the atom -will be ignored and not contribute to any bin averages. If {discard} -is set to {no}, the atom will be counted as if it were in the first or -last bin in that dimension. If (discard} is set to {mixed}, which is -the default, it will only be counted in the first or last bin if bins -extend to the box boundary in that dimension. This is the case if the -{bound} keyword settings are {lower} and {upper}, which is the -default. If the {bound} keyword settings are numeric values, then the -atom will be ignored if it is outside the bounds of any bin. Note -that in this case, it is possible that the first or last bin extends -beyond the numeric {bounds} settings, depending on the specified -{origin}. If this is the case, the atom is only ignored if it is -outside the first or last bin, not if it is simply outside the numeric -{bounds} setting. - -For orthogonal simulation boxes, the bins are also layers, pencils, or -boxes aligned with the xyz coordinate axes. For triclinic -(non-orthogonal) simulation boxes, the bins are so that they are -parallel to the tilted faces of the simulation box. See "this -section"_Section_howto.html#howto_12 of the manual for a discussion of -the geometry of triclinic boxes in LAMMPS. As described there, a -tilted simulation box has edge vectors a,b,c. In that nomenclature, -bins in the x dimension have faces with normals in the "b" cross "c" -direction. Bins in y have faces normal to the "a" cross "c" -direction. And bins in z have faces normal to the "a" cross "b" -direction. Note that in order to define the size and position of -these bins in an unambiguous fashion, the {units} option must be set -to {reduced} when using a triclinic simulation box, as noted below. - -:line - -The atom attribute values (vx,vy,vz,fx,fy,fz) are self-explanatory. -Note that other atom attributes (including atom postitions x,y,z) can -be used as inputs to this fix by using the "compute -property/atom"_compute_property_atom.html command and then specifying -an input value from that compute. - -The {density/number} value means the number density is computed in -each bin, i.e. a weighting of 1 for each atom. The {density/mass} -value means the mass density is computed in each bind, i.e. each atom -is weighted by its mass. The resulting density is normalized by the -volume of the bin so that units of number/volume or density are -output. See the "units"_units.html command doc page for the -definition of density for each choice of units, e.g. gram/cm^3. - -If a value begins with "c_", a compute ID must follow which has been -previously defined in the input script. If no bracketed integer is -appended, the per-atom vector calculated by the compute is used. If a -bracketed integer is appended, the Ith column of the per-atom array -calculated by the compute is used. Users can also write code for -their own compute styles and "add them to LAMMPS"_Section_modify.html. - -If a value begins with "f_", a fix ID must follow which has been -previously defined in the input script. If no bracketed integer is -appended, the per-atom vector calculated by the fix is used. If a -bracketed integer is appended, the Ith column of the per-atom array -calculated by the fix is used. Note that some fixes only produce -their values on certain timesteps, which must be compatible with -{Nevery}, else an error results. Users can also write code for their -own fix styles and "add them to LAMMPS"_Section_modify.html. - -If a value begins with "v_", a variable name must follow which has -been previously defined in the input script. Variables of style -{atom} can reference thermodynamic keywords and various per-atom -attributes, or invoke other computes, fixes, or variables when they -are evaluated, so this is a very general means of generating per-atom -quantities to spatially average. - -:line - -Additional optional keywords also affect the operation of this fix. -The {region}, {bound}, and {discard} keywords were discussed above. - -The {norm} keyword affects how averaging is done for the output -produced every {Nfreq} timesteps. For an {all} setting, a bin -quantity is summed over all atoms in all {Nrepeat} samples, as is the -count of atoms in the bin. The printed value for the bin is -Total-quantity / Total-count. In other words it is an average over -the entire {Nfreq} timescale. - -For a {sample} setting, the bin quantity is summed over atoms for only -a single sample, as is the count, and a "average sample value" is -computed, i.e. Sample-quantity / Sample-count. The printed value for -the bin is the average of the {Nrepeat} "average sample values", In -other words it is an average of an average. - -The {ave} keyword determines how the bin values produced every {Nfreq} -steps are averaged with bin values produced on previous steps that -were multiples of {Nfreq}, before they are accessed by another output -command or written to a file. - -If the {ave} setting is {one}, then the bin values produced on -timesteps that are multiples of {Nfreq} are independent of each other; -they are output as-is without further averaging. - -If the {ave} setting is {running}, then the bin values produced on -timesteps that are multiples of {Nfreq} are summed and averaged in a -cumulative sense before being output. Each output bin value is thus -the average of the bin value produced on that timestep with all -preceding values for the same bin. This running average begins when -the fix is defined; it can only be restarted by deleting the fix via -the "unfix"_unfix.html command, or re-defining the fix by -re-specifying it. - -If the {ave} setting is {window}, then the bin values produced on -timesteps that are multiples of {Nfreq} are summed and averaged within -a moving "window" of time, so that the last M values for the same bin -are used to produce the output. E.g. if M = 3 and Nfreq = 1000, then -the output on step 10000 will be the average of the individual bin -values on steps 8000,9000,10000. Outputs on early steps will average -over less than M values if they are not available. - -The {units} keyword determines the meaning of the distance units used -for the bin size {delta} and for {origin} and {bounds} values if they -are coordinate value. For orthogonal simulation boxes, any of the 3 -options may be used. For non-orthogonal (triclinic) simulation boxes, -only the {reduced} option may be used. - -A {box} value selects standard distance units as defined by the -"units"_units.html command, e.g. Angstroms for units = real or metal. -A {lattice} value means the distance units are in lattice spacings. -The "lattice"_lattice.html command must have been previously used to -define the lattice spacing. A {reduced} value means normalized -unitless values between 0 and 1, which represent the lower and upper -faces of the simulation box respectively. Thus an {origin} value of -0.5 means the center of the box in any dimension. A {delta} value of -0.1 means 10 bins span the box in that dimension. - -Consider a non-orthogonal box, with bins that are 1d layers or slabs -in the x dimension. No matter how the box is tilted, an {origin} of -0.0 means start layers at the lower "b" cross "c" plane of the -simulation box and an {origin} of 1.0 means to start layers at the -upper "b" cross "c" face of the box. A {delta} value of 0.1 means -there will be 10 layers from 0.0 to 1.0, regardless of the current -size or shape of the simulation box. - -The {file} keyword allows a filename to be specified. Every {Nfreq} -timesteps, a section of bin info will be written to a text file in the -following format. A line with the timestep and number of bin is -written. Then one line per bin is written, containing the bin ID -(1-N), the coordinate of the center of the bin, the number of atoms -in the bin, and one or more calculated values. The number of values -in each line corresponds to the number of values specified in the fix -ave/spatial command. The number of atoms and the value(s) are average -quantities. If the value of the {units} keyword is {box} or -{lattice}, the "coord" is printed in box units. If the value of the -{units} keyword is {reduced}, the "coord" is printed in reduced units -(0-1). - -The {overwrite} keyword will continuously overwrite the output file -with the latest output, so that it only contains one timestep worth of -output. This option can only be used with the {ave running} setting. - -The {title1} and {title2} and {title3} keywords allow specification of -the strings that will be printed as the first 3 lines of the output -file, assuming the {file} keyword was used. LAMMPS uses default -values for each of these, so they do not need to be specified. - -By default, these header lines are as follows: - -# Spatial-averaged data for fix ID and group name -# Timestep Number-of-bins -# Bin Coord1 Coord2 Coord3 Count value1 value2 ... :pre - -In the first line, ID and name are replaced with the fix-ID and group -name.

For 1d bins, the word Coord1 is replaced by -just Coord. - -:line - -[Restart, fix_modify, output, run start/stop, minimize info:] - -No information about this fix is written to "binary restart -files"_restart.html. None of the "fix_modify"_fix_modify.html options -are relevant to this fix. - -This fix computes a global array of values which can be accessed by -various "output commands"_Section_howto.html#howto_15. The values can -only be accessed on timesteps that are multiples of {Nfreq} since that -is when averaging is performed. The global array has # of rows = -Nbins and # of columns = Ndim+1+Nvalues, where Ndim = 1,2,3 for -1d,2d,3d bins. The first 1 or 2 or 3 columns have the bin coordinates -(center of the bin) in the appropriate dimensions, the next column has -the count of atoms in that bin, and the remaining columns are the -Nvalue quantities. When the array is accessed with an I that exceeds -the current number of bins, than a 0.0 is returned by the fix instead -of an error, since the number of bins can vary as a simulation runs, -depending on the simulation box size. 2d or 3d bins are ordered so -that the last dimension(s) vary fastest.

If the {region} keyword is used, the atom -must be in both the group and the specified geometric -"region"_region.html in order to contribute to bin averages. - -Each listed value can be an atom attribute (position, velocity, force -component), a mass or number density, or the result of a -"compute"_compute.html or "fix"_fix.html or the evaluation of an -atom-style "variable"_variable.html. In the latter cases, the -compute, fix, or variable must produce a per-atom quantity, not a -global quantity. If you wish to time-average global quantities from a -compute, fix, or variable, then see the "fix -ave/time"_fix_ave_time.html command. - -"Computes"_compute.html that produce per-atom quantities are those -which have the word {atom} in their style name. See the doc pages for -individual "fixes"_fix.html to determine which ones produce per-atom -quantities. "Variables"_variable.html of style {atom} are the only -ones that can be used with this fix since all other styles of variable -produce global quantities. - -The per-atom values of each input vector are binned and averaged -independently of the per-atom values in other input vectors. - -{Nbins} specifies the number of spherical shells which will be created -between r_min and r_max centered at (origin_x, origin_y, origin_z). - -NOTE: This fix works by creating an array of size Nbins by Nvalues on -each processor. Nbins is the total number of bins; Nvalues is the -number of input values specified. Each processor loops over its -atoms, tallying its values to the appropriate bin. Then the entire -array is summed across all processors. This means that using a large -number of bins will incur an overhead in memory and computational cost -(summing across processors), so be careful to use reasonable numbers -of bins. - -:line - -The {Nevery}, {Nrepeat}, and {Nfreq} arguments specify on what -timesteps the input values will be used to bin them and contribute to -the average. The final averaged quantities are generated on timesteps -that are a multiples of {Nfreq}. The average is over {Nrepeat} -quantities, computed in the preceding portion of the simulation every -{Nevery} timesteps. {Nfreq} must be a multiple of {Nevery} and -{Nevery} must be non-zero even if {Nrepeat} is 1. -Also, the timesteps -contributing to the average value cannot overlap, -i.e. Nrepeat*Nevery can not exceed Nfreq. - -For example, if Nevery=2, Nrepeat=6, and Nfreq=100, then values on -timesteps 90,92,94,96,98,100 will be used to compute the final average -on timestep 100. Similarly for timesteps 190,192,194,196,198,200 on -timestep 200, etc. If Nrepeat=1 and Nfreq = 100, then no time -averaging is done; values are simply generated on timesteps -100,200,etc. - -:line - -The {origin_x}, {origin_y}, and {origin_z} parameters may be specified -by either a compute or a variable. This allows, for example, the -center of the spherical bins to be attached to the center of mass of a -group of atoms. If a variable origin is used and periodic boundary -conditions are in effect, then the origin will be wrapped across -periodic boundaries whenever it changes so that it is always inside -the simulation box. - -:line - -The atom attribute values (vx,vy,vz,fx,fy,fz) are self-explanatory. -Note that other atom attributes (including atom postitions x,y,z) can -be used as inputs to this fix by using the "compute -property/atom"_compute_property_atom.html command and then specifying -an input value from that compute. - -The {density/number} value means the number density is computed in -each bin, i.e. a weighting of 1 for each atom. The {density/mass} -value means the mass density is computed in each bin, i.e. each atom -is weighted by its mass. The resulting density is normalized by the -volume of the bin so that units of number/volume or density are -output. See the "units"_units.html command doc page for the -definition of density for each choice of units, e.g. gram/cm^3. -The bin volume will always be calculated in box units, independent -of the use of the {units} keyword in this command. - -If a value begins with "c_", a compute ID must follow which has been -previously defined in the input script. If no bracketed integer is -appended, the per-atom vector calculated by the compute is used.

If no bracketed integer is -appended, the per-atom vector calculated by the fix is used. If a -bracketed integer is appended, the Ith column of the per-atom array -calculated by the fix is used.

For an {all} setting, a bin -quantity is summed over all atoms in all {Nrepeat} samples, as is the -count of atoms in the bin. The printed value for the bin is -Total-quantity / Total-count. In other words it is an average over -the entire {Nfreq} timescale. - -For a {sample} setting, the bin quantity is summed over atoms for only -a single sample, as is the count, and a "average sample value" is -computed, i.e. Sample-quantity / Sample-count. The printed value for -the bin is the average of the {Nrepeat} "average sample values", In -other words it is an average of an average. - -The {ave} keyword determines how the bin values produced every {Nfreq} -steps are averaged with bin values produced on previous steps that -were multiples of {Nfreq}, before they are accessed by another output -command or written to a file. - -If the {ave} setting is {one}, then the bin values produced on -timesteps that are multiples of {Nfreq} are independent of each other; -they are output as-is without further averaging. - -If the {ave} setting is {running}, then the bin values produced on -timesteps that are multiples of {Nfreq} are summed and averaged in a -cumulative sense before being output. Each output bin value is thus -the average of the bin value produced on that timestep with all -preceding values for the same bin. This running average begins when -the fix is defined; it can only be restarted by deleting the fix via -the "unfix"_unfix.html command, or re-defining the fix by -re-specifying it. - -If the {ave} setting is {window}, then the bin values produced on -timesteps that are multiples of {Nfreq} are summed and averaged within -a moving "window" of time, so that the last M values for the same bin -are used to produce the output. E.g. if M = 3 and Nfreq = 1000, then -the output on step 10000 will be the average of the individual bin -values on steps 8000,9000,10000. Outputs on early steps will average -over less than M values if they are not available. - -The {units} keyword determines the meaning of the distance units used -for the sphere origin and the two radial lengths. For orthogonal -simulation boxes, any of the 3 options may be used.
