! Purpose: set initial FLD radiation solution field or parameters at 1st RKstg. 
!
! Description: none.
!
! Input: region = data of current region,
!        iStage = current RK stage.
!
! Output: region%levels%radi or global% = new solution or parameters at
!         beginning of each time step.
!
! Notes: none.
