Detailed Description

Variable Documentation

◆ 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 ( $k$, $R_{ij}$, $\varepsilon$, $\varphi$, $\bar{f}$, $\omega$, 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

◆ iphydr

integer(c_int), pointer, save iphydr

Improved pressure interpolation scheme. See cs_velocity_pressure_param_t::iphydr.

◆ 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])
