Function Documentation

cs_cf_cfl_compute()

void cs_cf_cfl_compute

(

cs_real_t

wcf[]

)

Computation of the constraint for the CFL (compressible algorithm)

Parameters

[in]

wcf

compressible constraint

cs_cf_convective_mass_flux()

void cs_cf_convective_mass_flux

(

int

iterns

)

Update the convective mass flux before the velocity prediction step. It is the first step of the compressible algorithm at each time iteration.

This function solves the continuity equation in pressure formulation and then updates the density and the mass flux.

Parameters

[in]

iterns

Navier-Stokes iteration number
