compute pressure/uef command¶
compute ID group-ID pressure/uef temp-ID keyword ...
ID, group-ID are documented in compute command
pressure/uef = style name of this compute command
temp-ID = ID of compute that calculates temperature, can be NULL if not needed
zero or more keywords may be appended
keyword = ke or pair or bond or angle or dihedral or improper or kspace or fix or virial
compute 1 all pressure/uef my_temp_uef compute 2 all pressure/uef my_temp_uef virial
This command is used to compute the pressure tensor in the reference frame of the applied flow field when fix nvt/uef or fix npt/uef is used. It is not necessary to use this command to compute the scalar value of the pressure. A compute pressure may be used for that purpose.
The keywords and output information are documented in compute_pressure.
This fix is part of the USER-UEF package. It is only enabled if LAMMPS was built with that package. See the Build package doc page for more info.
The kinetic contribution to the pressure tensor will be accurate only when the compute specified by temp-ID is a compute temp/uef.
