Purpose: ! ------- !> \file cs_user_initialization.f90 !> !> \brief Initialize variables !> !> See \subpage cs_user_initialization for examples. !> !> 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. !> !> Modification of the behaviour law of physical quantities (rom, viscl, !> viscls, cp) is not done here. It is the purpose of the user subroutine !> \ref usphyv (in cs_user_physical_properties.f90) !> !> \c rom and \c viscl values are equal to \c ro0 and \c viscl0 or initialize !> by reading the restart file. !> Variables diffusivity and specific heat (when they are defined) have no value !> except if they are read from a restart file. !> !> \par cs_user_initialization_cell_id Cells identification !> !> Cells may be identified using the \ref getcel subroutine. !> The syntax of this subroutine is described in the !> \ref cs_user_boundary_conditions subroutine, !> but a more thorough description can be found in the user guide. !> !> Field cell values arrays can be retrieved using the appropriate access !> functions as described \ref field "here". !> !> Example of field ids: !> - Density: \c irom !> - Dynamic molecular viscosity: \c iviscl !> - Turbulent viscosity: \c ivisct !> - Specific heat: \c icp !> - Diffusivity(lambda): \c field_get_key_int(ivarfl(isca(iscal)), !> kivisl, ...) !> ! !------------------------------------------------------------------------------- !------------------------------------------------------------------------------- !
