! Purpose: wait until data is received by other processors communicating
!          with the current region specific for PEUL Module.
!
! Description: none.
!
! Input: regions  = all regiona
!        iReg     = current region
!        geometry = true if geometrical data were send, false otherwise.
!
! Output: none.
!
! Notes: none.
