massed_pressure_gradient#
- ptrace.massed_pressure_gradient(p0: Any) int #
Specify the name of the pressure gradient variable used in the pressure force term of the massed-particle calculation.
The “ptrace: massed_particles” command does not have to be ON in order to specify this command. If “none” is specified, then the pressure force term is ignored in the massed-particle calculation. The default setting is “none”.- Examples:
# # Create a massless point trace # ensight.part.select_all() ensight.ptrace.select_default() ensight.part.modify_begin() ensight.ptrace.variable("velocity") ensight.part.modify_end() ensight.part.select_all() ensight.ptrace.create_pt() ensight.part.select_begin(2) # # Toggle on massed-particle pressure force term # Specify pressure gradient variable # ensight.part.modify_begin() ensight.ptrace.massed_pressure("ON") ensight.ptrace.massed_pressure_gradient("grad_pressure") ensight.part.modify_end() # # Change part to massed trace using current settings # ensight.part.modify_begin() ensight.ptrace.massed_particles("ON") ensight.part.modify_end()
- Returns:
zero on success, non-zero on error
