compute pressure/uef command

Syntax:

compute ID group-ID pressure/uef temp-ID keyword ... 

Examples:

compute 1 all pressure/uef my_temp_uef
compute 2 all pressure/uef my_temp_uef virial 

Description:

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.

Restrictions:

This fix is part of the USER-UEF package. It is only enabled if LAMMPS was built with that package. See the Making LAMMPS section for more info.

This command can only be used when fix nvt/uef or fix npt/uef is active.

The kinetic contribution to the pressure tensor will be accurate only when the compute specified by temp-ID is a compute temp/uef.

Related commands:

compute pressure, fix nvt/uef, compute temp/uef

Default: none
