reference specific heat.
Useful if there is 1 <= n <= nscaus. So that iscsth(n)=1 (there is a scalar "temperature"), unless the user specifies the specific heat in the user subroutine {usphyv} (icp > 0) with the compressible module or coal combustion, cp0 is also needed even when there is no user scalar.

reference value for the reduced pressure (see ro0). It is especially used to initialise the reduced pressure and as a reference value for the outlet boundary conditions. For an optimised precision in the resolution of
, it is wiser to keep pred0 to 0. With the compressible module, the "pressure" variable appearing in the equations directly represents the total pressure. It is therefore initialised to p0 and not pred0 (see ro0). Always useful, except with the compressible module

reference density. Negative value: not initialised. Its value is not used in gas or coal combustion modelling (it will be calculated following the perfect gas law, with and
). With the compressible module, it is also not used by the code, but it may be (and often is) referenced by the user in user subroutines; it is therefore better to specify its value.
Always useful otherwise, even if a law defining the density is given by the user subroutines usphyv or uselph. indeed, except with the compressible module, CS does not use the total pressure when solving the Navier-Stokes equation, but a reduced pressure .

are reference values (see pred0 and p0). Hence, the term

. The closer ro0 is to the value of

appear in the listing and the post-processing outputs.. with the compressible module, the calculation is made directly on the total pressure

Useful for the specific physics gas or coal combustion (initialisation of the density), for the electricity modules to initialise the domain temperature and for the compressible module (initialisations). It must be given in Kelvin.
