momentum

vortexcore.momentum(p0: Any) → int

Specify the momentum variable to use in creating/updating a vortex core part or the default attributes.

This variable is assigned automatically if the variable name <Momentum> exists.

Since the computation of separation and attachment lines depend on velocity, either the velocity variable must be defined or both the density and momentum variables must be defined to obtain the velocity variable.

Args:

p0:

‘variable_name’ name of the momentum variable (the default name <none> means to use nothing)

Examples:

ensight.variables.activate("Momentum")
ensight.vortexcore.select_default()
ensight.part.modify_begin()
ensight.vortexcore.momentum("Momentum")
ensight.part.modify_end()

Returns:

zero on success, non-zero on error
