user_defined_functions

class ansys.fluent.core.solver.settings_231.user_defined_functions.user_defined_functions(name=None, parent=None)

Main menu to set DPM user-defined functions. User-defined functions can be used to customize the discrete phase model to include additional body forces, modify interphase exchange terms (sources), calculate or integrate scalar values along the particle trajectory, and more.

Parent	Summary
discrete_phase	Toplevel menu of the Discrete Phase multiphase model. A discrete phase model (DPM) is used when the aim is to investigate the behavior of the particles from a Lagrangian view and a discrete perspective.
