user_defined_functions

class ansys.fluent.core.generated.solver.settings_251.user_defined_functions(name=None, parent=None)

Bases: Group

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.

Attributes

source_terms	Specify the name of the DPM source function.
erosion_accretion	Specify the name of the DPM erosion/accretion function.
output	Specify the name of the DPM output function.
scalar_update	Specify the name of the DPM scalar update function.
collision	Specify the name of the DPM collision function.
dpm_time_step_size	Specify the name of the DPM timestep function.
impingement_model	Specify the name of the impingement model function.
film_regime	Specify the name of the film regime function.
splashing_distribution	Specify the name of the splashing distribution function.

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.
