Detailed Description

Stokes equation model descriptor.

Members of these Stokes equation model descriptor are publicly accessible, to allow for concise syntax, as it is expected to be used in many places.

Field Documentation

fluid_solid

bool fluid_solid

Has a solid zone where dynamics must be killed?

• false (default)
• true

idilat

int idilat

algorithm to take into account the density variation in time

• 0: Boussinesq approximation (rho constant except in the buoyant term where
• 1: dilatable steady algorithm (default)
• 2: dilatable unsteady algorithm
• 3: low-Mach algorithm
• 4: algorithm for fire

iprcdo

int iprcdo

Indicate discretization method for presssure

• 0: Use Legacy Finite Volume method
• 1: Use CDO method, if CDO/FV is coupled

ivisse

int ivisse

Indicates whether the source terms in transposed gradient and velocity divergence should be taken into account in the momentum equation. In the compressible module, these terms also account for the volume viscosity (cf. viscv0 and iviscv) :

• 0: not taken into account,
• 1: taken into account.

n_buoyant_scal

int n_buoyant_scal
