momentum

boundarylayer.momentum(p0: Any) → int

Specify the momentum variable to use in creating/updating the boundary-layer variables.

This variable gets assigned automatically if the variable name <momentum> exists. Since the computation of boundary-layer variables 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.boundarylayer.modify_begin()
ensight.boundarylayer.momentum("none")
ensight.boundarylayer.modify_end()

Returns:

zero on success, non-zero on error
