[Syntax:]
|
||
|
|
|
||
|
|
fix_modify fix-ID keyword value ... :pre
|
||
|
|
|
||
|
|
fix-ID = ID of the fix to modify :ulb,l
|
||
|
|
one or more keyword/value pairs may be appended :l
|
||
|
|
keyword = {temp} or {energy} or {thermo} :l
|
||
|
|
{temp} value = temperature ID
|
||
|
|
{energy} value = {yes} or {no}
|
||
|
|
{thermo} value = {yes} or {no} :pre
|
||
|
|
:ule
|
||
|
|

[Examples:]
|
||
|
|
|
||
|
|
fix_modify 3 temp myTemp
|
||
|
|
fix_modify 1 thermo yes energy no :pre

[Description:]
|
||
|
|
|
||
|
|
Modify one or more parameters of a previously defined fix. Not all
|
||
|
|
fix styles support all parameters.
|
||
|
|
|
||
|
|
The {temp} keyword is used to determine how a fix computes
|
||
|
|
temperature. The specified temperature ID must have been previously
|
||
|
|
defined by the user via the "temperature"_temperature.html command.
|
||
|
|
The default setting for {temp} is temperature ID = {default}. Fix
|
||
|
|
styles that use the {temp} setting are
|
||
|
|
"temp/rescale"_fix_temp_rescale.html, "nvt"_fix_nvt.html, and
|
||
|
|
"npt"_fix_npt.html.
|
||
|
|
|
||
|
|
The {energy} and {thermo} keywords enable a fix to compute and/or
|
||
|
|
print quantities as part of the thermodynamic output to the screen and
|
||
|
|
log file (if the fix defines such quantites). When the {energy}
|
||
|
|
keyword is set to {yes}, the fix computes a contribution to the total
|
||
|
|
potential energy that is printed as PotEng during thermodynamic
|
||
|
|
output. When the {thermo} keyword is set to yes, the fix prints one
|
||
|
|
or more values that are appended to the list of thermodynamic outputs.
|
||
|
|
See the "thermo_style"_thermo_style.html command for how this printing
|
||
|
|
is formatted.
|
||
|
|
|
||
|
|
The fixes that support the {energy} and {thermo} options include: "fix
|
||
|
|
indent"_fix_indent.html, "fix nvt"_fix_nvt.html, "fix
|
||
|
|
nph"_fix_nph.html, "fix npt"_fix_npt.html, "fix
|
||
|
|
orient/fcc"_fix_orient_fcc.html, "fix
|
||
|
|
temp/rescale"_fix_temp_rescale.html, and "fix
|
||
|
|

|
||
|
|
more info on what is computed and/or printed.
