RoeFlux

class RoeFlux

Bases: Flow360BaseModel

RoeFlux class for the Roe flux-difference splitting Riemann solver.

Example

>>> fl.RoeFlux()
>>> fl.RoeFlux(numerical_dissipation_factor=0.2, low_mach_preconditioner=True)

Attributes

numerical_dissipation_factor: float

A factor in the range [0.01, 1.0] which exponentially reduces the dissipation of the numerical flux. The recommended starting value for most low-dissipation runs is 0.2.

Default:

1

low_mach_preconditioner: bool

Use preconditioning for accelerating low Mach number flows.

Default:

False

low_mach_preconditioner_threshold: float, optional

For flow regions with Mach numbers smaller than threshold, the input Mach number to the preconditioner is assumed to be the threshold value if it is smaller than the threshold. The default value for the threshold is the freestream Mach number.

Default:

None
