The main documentation of the Initialized_Multi_Mesh Procedure contains additional explanation of this code listing.
function Initialized_Multi_Mesh (Mesh) result(Initialized) ! Use associations. use Caesar_Flags_Module, only: initialized_flag ! Input variable. ! Multi_Mesh to be checked. type(Multi_Mesh_type), intent(in) :: Mesh ! Output variable. type(logical) :: Initialized ! Initialized condition boolean. !~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ! Verify requirements - none. ! Set initialized boolean. Initialized = Mesh%Initialized == initialized_flag ! Verify guarantees - none. return end function Initialized_Multi_Mesh
