underrelaxation_factor

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

Bases: Real

Sets the under-relaxation factor for DPM source terms. Controls damping of DPM source term updates (typically 0 - 1). Lower values improve stability in strongly coupled cases, but require more DPM tracking cycles so that the full source term strength will be applied to the transport equations. For transient flows a value of 0.9 or higher is recommended.
