7.17.1.20.50. Pressure_Material_Derivative

Syntax

Source For Energy [{of} SpeciesName | {in} MaterialPhaseName | {ls} {a | b | c}] {@ | at | for | on | over} MeshPartIdentifier = Pressure_Material_Derivative [Power_Output = power_output | Toggle = toggle | Multiplier = multiplier]

Summary

Pressure material derivative source for energy equation

Description

S = M \left( \pd{P}{t} + v \cdot \nabla P \right)

The following options are present in most boundary conditions/sources. The meaning of each option is as follows:

Power_Output

If specified, the total (integrated) power of the given BC/Src is calculated and stored into the global variable name specified as the power_output argument.

Toggle

If given, specifies which toggle block controls whether this BC is active or not.
