! Purpose: write flow solution to file for one region (only mixture for now).
!
! Description: the following solution formats are supported:
!              - RocfloMP ASCII
!              - RocfloMP binary.
!
! Input: regions            = dimensions and cons. variables of all regions
!        iReg               = region number
!        global%currentTime = physical time
!        global%resInit     = initial residual.
!
! Output: to file.
!
! Notes: solution is stored only for the current grid level; it is also
!        stored for all dummy cells. All regions are written into one file.
!        There is no transfer of data from other processors.
