Functions/Subroutines

subroutine cs_user_initialization (nvar, nscal, dt)
 

Detailed Description

Initialize variables.

This subroutine is called at beginning of the computation (restart or not) before the loop time step.

This subroutine enables to initialize or modify (for restart) unkown variables and time step values.

rom and viscl values are equal to ro0 and viscl0 or initialize by reading the restart file. viscls and cp variables (when there are defined) have no value excepted if they are read from a restart file.

Physical quantities are defined in the following arrays:

propce ! physical quantities defined at cell center

Examples:

propce(iel, ipproc(irom )) ! means rom (iel)
propce(iel, ipproc(iviscl)) ! means viscl(iel)
propce(iel, ipproc(icp )) ! means cp (iel)
propce(iel, ipproc(ivisls(iscal))) ! means visls(iel, iscal)

Modification of the behaviour law of physical quantities (rom, viscl, viscls, cp) is not done here. It is the purpose of the user subroutine cs_user_physical_properties.

Cells identification of some variables

Cells may be identified using the getcel subroutine. The syntax of this subroutine is described in the cs_user_boundary_conditions subroutine, but a more thorough description can be found in the user guide.
