compressibility_control#

class ansys.cfx.core.generated.pre_processing.settings_261.compressibility_control.compressibility_control(name: str | None = None, parent=None)#

Bases: Group

Holds parameters that affect solver convergence for compressible flows.

Attributes

Attribute

Summary

enabled

Enable the COMPRESSIBILITY CONTROL object.

high_speed_numerics

Activates special numerics to improve solver behavior for high speed flow (e.g. with shocks).

carbuncle_fix

Activates special numerics to workaround carbuncle effect. Activated by default when High Speed Numerics is activated.

compressible_linearisation

Determines whether drho/dp is used to linearize density derivatives in the continuity equation.

decreasing_pressure_relaxation

Determines whether the rate of pressure decrease is restricted for compressible flows.

decreasing_pressure_relaxation_factor

Maximum rate of pressure decrease in an iteration.

decreasing_temperature_relaxation

Determines whether the rate of temperature decrease is restricted for compressible flows.

decreasing_temperature_relaxation_factor

Maximum rate of temperature decrease in an iteration.

total_pressure_option

Recipe to use for static-to-total pressure conversions.

clip_pressure_for_properties

Specifies whether pressure should be clipped when calculating properties for compressible simulations. If activated, negative solution pressures are permitted.

minimum_pressure_for_properties

Minimum absolute pressure for properties if negative absolute pressures are permitted for compressible simulations.
