Detailed Description

Variable Documentation

◆ arak

real(c_double), pointer, save arak

Arakawa multiplicator for the Rhie and Chow filter (1 by default)

◆ epsdp

real(c_double), pointer, save epsdp

parameter of diagonal pressure strengthening

◆ fluid_solid

logical(c_bool), pointer, save fluid_solid

Has a solid zone where dynamics must be killed?

false (default)
true

◆ icalhy

integer(c_int), pointer, save icalhy

compute the hydrostatic pressure in order to compute the Dirichlet conditions on the pressure at outlets

1: true
0: false (default)

◆ iccvfg

integer(c_int), pointer, save iccvfg

indicates whether the dynamic field should be frozen or not:

1: true
0: false (default)
In such a case, the values of velocity, pressure and the variables related to the potential turbulence model ( , $R_{ij}$ , $\varepsilon$ , $\varphi$ , $\bar{f}$ , $\omega$ , turbulent viscosity) are kept constant over time and only the equations for the scalars are solved.
Also, if iccvfg = 1, the physical properties modified in cs_user_physical_properties will keep being updated. Beware of non-consistencies if these properties would normally affect the dynamic field (modification of density for instance).
Useful if and only if nscal 0 and the calculation is a restart.

◆ idilat

integer(c_int), pointer, save idilat

Algorithm to take into account the density variation in time.

0: boussinesq algorithm with constant density
1: dilatable steady algorithm (default)
2: dilatable unsteady algorithm
3: low-Mach algorithm
4: algorithm for fire

0: no face
1: at least one face

◆ iphydr

1: reinforced coupling in case calculation with long time steps
Always useful (it is seldom advised, but it can prove very useful, for instance, in case of flows with weak convection effects and highly variable viscosity).

◆ irecmf

integer(c_int), pointer, save irecmf

0: false (default) (see cs_boundary_condition_set_coeffs, useful in case of coupling with syrthes)

◆ itpcol

integer(c_int), pointer, save itpcol

Time scheme option:

0: staggered time scheme. On the time grids, the velocity is half a time step behind the density and the buoyant scalar. (See the thesis of [Pierce:2004])
1: collocated time scheme. On the time grids, the velocity is at the same location as the density and the buoyant scalar. (See [Ma:2019])

◆ ivisse

integer(c_int), pointer, save 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) $\partial_i \left[(\kappa -2/3\,(\mu+\mu_t))\partial_k U_k \right] + \partial_j \left[ (\mu+\mu_t)\partial_i U_j \right]$ :

0: not taken into account,
