class ansys.fluent.core.generated.solver.settings_271.physical_models(name=None, parent=None)#

Enables and configures physical submodels for the discrete phase.

Attributes

Attribute	Summary
particle_radiation_enabled	Enables interaction between particles and the radiation model.
particle_forces	Configures and enables forces acting on particles. Force models are critical in flows with strong gradients, ~%shear, buoyancy, or temperature differences where secondary forces significantly affect trajectories.
erosion_accretion_enabled	Enables modeling of wall erosion or accretion due to particle impact.
erosion_accretion_rate_accumulation_enabled	Accumulates erosion and accretion rates over multiple tracking passes.
pressure_dependent_boiling	For pressure-dependent boiling, the boiling temperature is
temperature_dependent_latent_heat	This option includes the droplet temperature effects on the latent heat,
twoway_turb_coupl_enabled	Enables modulation of carrier-phase turbulence due to particles.
secondary_breakup_enabled	Enables droplet breakup due to aerodynamic forces. Essential in high Weber-number flows where aerodynamic forces can fragment droplets.
volume_displacement	Configures fluid displacement effects due to particle volume. Relevant for dense particle loading where particle volume fraction affects fluid continuity and momentum equations.
wall_film	Controls physical modeling and numerical treatment of the Lagrangian thin-film model.

Parent	Summary
discrete_phase	Configures the Discrete Phase Model (DPM) to track particles, droplets, or bubbles in a Lagrangian framework.
