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

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.

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])
