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.

◆ idebty

integer, dimension(ntypmx), save idebty

◆ idilat

integer(c_int), pointer, save idilat

Algorithm to take into account the density variation in time.

1: dilatable steady algorithm (default)
2: dilatable unsteady algorithm
3: low-Mach algorithm
4: algorithm for fire

◆ iescal

integer, dimension(nestmx), save iescal

iescal indicates the calculation mode for the error estimator iespre, iesder, iescor or iestot for the Navier-Stokes equation:

0: estimator not calculated,
1: the estimator $\eta^{*}_{i,1}$ is calculated, without contribution of the volume,
2: the estimator $\eta^{*}_{i,2}$ is calculated, with contribution of the volume (norm ), except for iescor, for which $|\Omega_i|\ \eta^{corr}_{i,1}\$ is calculated. The names of the estimators appearing in the log and the post-processing are made up of the default name (given before), followed by the value of iescal}. For instance, EsPre2 is the estimator iespre calculated with iescal = 2.
