/* ERROR/WARNING messages:
|
|
|
|
E: Fix %s does not allow use of dynamic group
|
|
|
|
Dynamic groups have not yet been enabled for this fix.
|
|
|
|
E: Compute %s does not allow use of dynamic group
|
|
|
|
Dynamic groups have not yet been enabled for this compute.
|
|
|
|
W: One or more atoms are time integrated more than once
|
|
|
|
This is probably an error since you typically do not want to
|
|
advance the positions or velocities of an atom more than once
|
|
per timestep.
|
|
|
|
E: Illegal ... command
|
|
|
|
Self-explanatory. Check the input script syntax and compare to the
|
|
documentation for the command. You can use -echo screen as a
|
|
command-line option when running LAMMPS to see the offending line.
|
|
|
|
E: Fix command before simulation box is defined
|
|
|
|
The fix command cannot be used before a read_data, read_restart, or
|
|
create_box command.
|
|
|
|
E: Could not find fix group ID
|
|
|
|
A group ID used in the fix command does not exist.
|
|
|
|
E: Replacing a fix, but new style != old style
|
|
|
|
A fix ID can be used a 2nd time, but only if the style matches the
|
|
previous fix. In this case it is assumed you with to reset a fix's
|
|
parameters. This error may mean you are mistakenly re-using a fix ID
|
|
when you do not intend to.
|
|
|
|
W: Replacing a fix, but new group != old group
|
|
|
|
The ID and style of a fix match for a fix you are changing with a fix
|
|
command, but the new group you are specifying does not match the old
|
|
group.
|
|
|
|
E: Unknown fix style
|
|
|
|
The choice of fix style is unknown.
|
|
|
|
E: Could not find fix_modify ID
|
|
|
|
A fix ID used in the fix_modify command does not exist.
|
|
|
|
E: Could not find fix ID to delete
|
|
|
|
Self-explanatory.
|
|
|
|
E: Reuse of compute ID
|
|
|
|
A compute ID cannot be used twice.
|
|
|
|
E: Unknown compute style
|
|
|
|
The choice of compute style is unknown.
|
|
|
|
E: Could not find compute_modify ID
|
|
|
|
Self-explanatory.
|
|
|
|
E: Could not find compute ID to delete
|
|
|
|
Self-explanatory.
