<A NAME = "cmd_1"></A><H4>3.1 LAMMPS input script
|
|
</H4>
|
|
<P>LAMMPS executes by reading commands from a input script (text file),
|
|
one line at a time. When the input script ends, LAMMPS exits. Each
|
|
command causes LAMMPS to take some action. It may set an internal
|
|
variable, read in a file, or run a simulation. Most commands have
|
|
default settings, which means you only need to use the command if you
|
|
wish to change the default.
|
|
</P>
|
|
<P>In many cases, the ordering of commands in an input script is not
|
|
important. However the following rules apply:
|
|
</P>
|
|
<P>(1) LAMMPS does not read your entire input script and then perform a
|
|
simulation with all the settings. Rather, the input script is read
|
|
one line at a time and each command takes effect when it is read.
|
|
Thus this sequence of commands:
|
|
</P>
|
|
<PRE>timestep 0.5
|
|
run 100
|
|
run 100
|
|
</PRE>
|
|
<P>does something different than this sequence:
|
|
</P>
|
|
<PRE>run 100
|
|
timestep 0.5
|
|
run 100
|
|
</PRE>
|
|
<P>In the first case, the specified timestep (0.5 fmsec) is used for two
|
|
simulations of 100 timesteps each. In the 2nd case, the default
|
|
timestep (1.0 fmsec) is used for the 1st 100 step simulation and a 0.5
|
|
fmsec timestep is used for the 2nd one.
|
|
</P>
|
|
<P>(2) Some commands are only valid when they follow other commands. For
|
|
example you cannot set the temperature of a group of atoms until atoms
|
|
have been defined and a group command is used to define which atoms
|
|
belong to the group.
|
|
</P>
|
|
<P>(3) Sometimes command B will use values that can be set by command A.
|
|
This means command A must precede command B in the input script if it
|
|
is to have the desired effect. For example, the
|
|
<A HREF = "read_data.html">read_data</A> command initializes the system by setting
|
|
up the simulation box and assigning atoms to processors. If default
|
|
values are not desired, the <A HREF = "processors.html">processors</A> and
|
|
<A HREF = "boundary.html">boundary</A> commands need to be used before read_data to
|
|
tell LAMMPS how to map processors to the simulation box.
|
|
</P>
|
|
<P>Many input script errors are detected by LAMMPS and an ERROR or
|
|
WARNING message is printed. <A HREF = "Section_errors.html">This section</A> gives
|
|
more information on what errors mean. The documentation for each
|
|
command lists restrictions on how the command can be used.
|
|
</P>

|
|
|
<A NAME = "cmd_2"></A><H4>3.2 Parsing rules
|
|
</H4>
|
|
<P>Each non-blank line in the input script is treated as a command.
|
|
LAMMPS commands are case sensitive. Command names are lower-case, as
|
|
are specified command arguments. Upper case letters may be used in
|
|
file names or user-chosen ID strings.
|
|
</P>
|
|
<P>Here is how each line in the input script is parsed by LAMMPS:
|
|
</P>
|
|
<P>(1) If the last printable character on the line is a "&" character
|
|
(with no surrounding quotes), the command is assumed to continue on
|
|
the next line. The next line is concatenated to the previous line by
|
|
removing the "&" character and newline. This allows long commands to
|
|
be continued across two or more lines.
|
|
</P>
|
|
<P>(2) All characters from the first "#" character onward are treated as
|
|
comment and discarded. See an exception in (6). Note that a
|
|
comment after a trailing "&" character will prevent the command from
|
|
continuing on the next line. Also note that for multi-line commands a
|
|
single leading "#" will comment out the entire command.
|
|
</P>
|
|
<P>(3) The line is searched repeatedly for $ characters, which indicate
|
|
variables that are replaced with a text string. See an exception in
|
|
(6).
|
|
</P>
|
|
<P>If the $ is followed by curly brackets, then the variable name is the
|
|
text inside the curly brackets. If no curly brackets follow the $,
|
|
then the variable name is the single character immediately following
|
|
the $. Thus ${myTemp} and $x refer to variable names "myTemp" and
|
|
"x".
|
|
</P>
|
|
<P>How the variable is converted to a text string depends on what style
|
|
of variable it is; see the <A HREF = "variable">variable</A> doc page for details.
|
|
It can be a variable that stores multiple text strings, and return one
|
|
of them. The returned text string can be multiple "words" (space
|
|
separated) which will then be interpreted as multiple arguments in the
|
|
input command. The variable can also store a numeric formula which
|
|
will be evaluated and its numeric result returned as a string.
|
|
</P>
|
|
<P>As a special case, if the $ is followed by parenthesis, then the text
|
|
inside the parenthesis is treated as an "immediate" variable and
|
|
evaluated as an <A HREF = "variable.html">equal-style variable</A>. This is a way
|
|
to use numeric formulas in an input script without having to assign
|
|
them to variable names. For example, these 3 input script lines:
|
|
</P>
|
|
<PRE>variable X equal (xlo+xhi)/2+sqrt(v_area)
|
|
region 1 block $X 2 INF INF EDGE EDGE
|
|
variable X delete
|
|
</PRE>
|
|
<P>can be replaced by
|
|
</P>
|
|
<PRE>region 1 block $((xlo+xhi)/2+sqrt(v_area)) 2 INF INF EDGE EDGE
|
|
</PRE>
|
|
<P>so that you do not have to define (or discard) a temporary variable X.
|
|
</P>
|
|
<P>Note that neither the curly-bracket or immediate form of variables can
|
|
contain nested $ characters for other variables to substitute for.
|
|
Thus you cannot do this:
|
|
</P>
|
|
<PRE>variable a equal 2
|
|
variable b2 equal 4
|
|
print "B2 = ${b$a}"
|
|
</PRE>
|
|
<P>Nor can you specify this $($x-1.0) for an immediate variable, but
|
|
you could use $(v_x-1.0), since the latter is valid syntax for an
|
|
<A HREF = "variable.html">equal-style variable</A>.
|
|
</P>
|
|
<P>See the <A HREF = "variable.html">variable</A> command for more details of how
|
|
strings are assigned to variables and evaluated, and how they can be
|
|
used in input script commands.
|
|
</P>
|
|
<P>(4) The line is broken into "words" separated by whitespace (tabs,
|
|
spaces). Note that words can thus contain letters, digits,
|
|
underscores, or punctuation characters.
|
|
</P>
|
|
<P>(5) The first word is the command name. All successive words in the
|
|
line are arguments.
|
|
</P>
|
|
<P>(6) If you want text with spaces to be treated as a single argument,
|
|
it can be enclosed in either double or single quotes. A long single
|
|
argument enclosed in quotes can even span multiple lines if the "&"
|
|
character is used, as described above. E.g.
|
|
</P>
|
|
<PRE>print "Volume = $v"
|
|
print 'Volume = $v'
|
|
variable a string "red green blue &
|
|
purple orange cyan"
|
|
if "$<I>steps</I> > 1000" then quit
|
|
</PRE>
|
|
<P>The quotes are removed when the single argument is stored internally.
|
|
</P>
|
|
<P>See the <A HREF = "dump_modify.html">dump modify format</A> or <A HREF = "print.html">print</A> or
|
|
<A HREF = "if.html">if</A> commands for examples. A "#" or "$" character that is
|
|
between quotes will not be treated as a comment indicator in (2) or
|
|
substituted for as a variable in (3).
|
|
</P>
|
|
<P>IMPORTANT NOTE: If the argument is itself a command that requires a
|
|
quoted argument (e.g. using a <A HREF = "print.html">print</A> command as part of an
|
|
<A HREF = "if.html">if</A> or <A HREF = "run.html">run every</A> command), then the double and
|
|
single quotes can be nested in the usual manner. See the doc pages
|
|
for those commands for examples. Only one of level of nesting is
|
|
allowed, but that should be sufficient for most use cases.

<H4><A NAME = "cmd_3"></A>3.3 Input script structure
|
|
</H4>
|
|
<P>This section describes the structure of a typical LAMMPS input script.
|
|
The "examples" directory in the LAMMPS distribution contains many
|
|
sample input scripts; the corresponding problems are discussed in
|
|
<A HREF = "Section_example.html">Section_example</A>, and animated on the <A HREF = "http://lammps.sandia.gov">LAMMPS
|
|
WWW Site</A>.
|
|
</P>
|
|
<P>A LAMMPS input script typically has 4 parts:
|
|
</P>
|
|
<OL><LI>Initialization
|
|
<LI>Atom definition
|
|
<LI>Settings
|
|
<LI>Run a simulation
|
|
</OL>
|
|
<P>The last 2 parts can be repeated as many times as desired. I.e. run a
|
|
simulation, change some settings, run some more, etc. Each of the 4
|
|
parts is now described in more detail. Remember that almost all the
|
|
commands need only be used if a non-default value is desired.
|
|
</P>
|
|
<P>(1) Initialization
|
|
</P>
|
|
<P>Set parameters that need to be defined before atoms are created or
|
|
read-in from a file.
|
|
</P>
|
|
<P>The relevant commands are <A HREF = "units.html">units</A>,
|
|
<A HREF = "dimension.html">dimension</A>, <A HREF = "newton.html">newton</A>,
|
|
<A HREF = "processors.html">processors</A>, <A HREF = "boundary.html">boundary</A>,
|
|
<A HREF = "atom_style.html">atom_style</A>, <A HREF = "atom_modify.html">atom_modify</A>.
|
|
</P>
|
|
<P>If force-field parameters appear in the files that will be read, these
|
|
commands tell LAMMPS what kinds of force fields are being used:
|
|
<A HREF = "pair_style.html">pair_style</A>, <A HREF = "bond_style.html">bond_style</A>,
|
|
<A HREF = "angle_style.html">angle_style</A>, <A HREF = "dihedral_style.html">dihedral_style</A>,
|
|
<A HREF = "improper_style.html">improper_style</A>.
|
|
</P>
|
|
<P>(2) Atom definition
|
|
</P>
|
|
<P>There are 3 ways to define atoms in LAMMPS. Read them in from a data
|
|
or restart file via the <A HREF = "read_data.html">read_data</A> or
|
|
<A HREF = "read_restart.html">read_restart</A> commands. These files can contain
|
|
molecular topology information. Or create atoms on a lattice (with no
|
|
molecular topology), using these commands: <A HREF = "lattice.html">lattice</A>,
|
|
<A HREF = "region.html">region</A>, <A HREF = "create_box.html">create_box</A>,
|
|
<A HREF = "create_atoms.html">create_atoms</A>. The entire set of atoms can be
|
|
duplicated to make a larger simulation using the
|
|
<A HREF = "replicate.html">replicate</A> command.
|
|
</P>
|
|
<P>(3) Settings
|
|
</P>
|
|
<P>Once atoms and molecular topology are defined, a variety of settings
|
|
can be specified: force field coefficients, simulation parameters,
|
|
output options, etc.
|
|
</P>
|
|
<P>Force field coefficients are set by these commands (they can also be
|
|
set in the read-in files): <A HREF = "pair_coeff.html">pair_coeff</A>,
|
|
<A HREF = "bond_coeff.html">bond_coeff</A>, <A HREF = "angle_coeff.html">angle_coeff</A>,

|
|
<A HREF = "special_bonds.html">special_bonds</A>.
|
|
</P>
|
|
<P>Various simulation parameters are set by these commands:
|
|
<A HREF = "neighbor.html">neighbor</A>, <A HREF = "neigh_modify.html">neigh_modify</A>,
|
|
<A HREF = "group.html">group</A>, <A HREF = "timestep.html">timestep</A>,

|
|
<A HREF = "min_style.html">min_style</A>, <A HREF = "min_modify.html">min_modify</A>.
|
|
</P>
|
|
<P>Fixes impose a variety of boundary conditions, time integration, and
|
|
diagnostic options. The <A HREF = "fix.html">fix</A> command comes in many flavors.
|
|
</P>
|
|
<P>Various computations can be specified for execution during a
|
|
simulation using the <A HREF = "compute.html">compute</A>,
|
|
<A HREF = "compute_modify.html">compute_modify</A>, and <A HREF = "variable.html">variable</A>
|
|
commands.
|
|
</P>
|
|
<P>Output options are set by the <A HREF = "thermo.html">thermo</A>, <A HREF = "dump.html">dump</A>,
|
|
and <A HREF = "restart.html">restart</A> commands.
|
|
</P>
|
|
<P>(4) Run a simulation
|
|
</P>
|
|
<P>A molecular dynamics simulation is run using the <A HREF = "run.html">run</A>
|
|
command. Energy minimization (molecular statics) is performed using
|
|
the <A HREF = "minimize.html">minimize</A> command. A parallel tempering
|
|
(replica-exchange) simulation can be run using the
|
|
<A HREF = "temper.html">temper</A> command.
