Error in sequential coupled Model

Hello all,

I´m trying to couple two 1D morphological models and one 2D morphological model sequentially.     

In the coupling section I defined the following

COUPLINGS {
        COUPLING {
            upstream_subdomain   = upstream_1D_model
            downstream_subdomain = 2D_model
            type                = sequential
             two_way_coupling     = no
            HYDRAULICS {
                 upstream_interface   = Outflow_upstream_1D_model
                 downstream_interface = Inflow_2D
            }
            BEDLOAD {
                upstream_interface   = Outflow_upstream_1D_model
                d ownstream_interface = Inflow_2D
             }
        }
        COUPLING {
            type                 = sequential
            upstream_subdomain   = 2D_model
            downstream_subdomain = downstream_1D_model
            HYDRAULICS {
                upstream_interface   = Outflow_2D
                downstream_interface = inflow_downstream_1D_model
            }
            BEDLOAD {
                upstream_interface   = Outflow_2D
                downstream_interface = inflow_downstream_1D_model
            }
        }

When starting the simulation, I get an error saying:

"-> A sequential coupling has no upstream interface defined (BEDLOAD).
   Please check the definition of the coupling.
   Program can not continue.
-> Domain: Simulation stopped due to errors"

Individually, both models run without any problems (hydraulics and morphodynamics), so does the coupled model runs without bedload. How do I set up the interface for the bedload correctly?

Thanks in advance!!

Re: Error in sequential coupled Model

Actually, the bedload interfaces have unique names (different than the hydraulic ones)

COUPLINGS {
        COUPLING {
            upstream_subdomain   = upstream_1D_model
            downstream_subdomain = 2D_model
            type                = sequential
             two_way_coupling     = no
            HYDRAULICS {
                 upstream_interface   = Outflow_upstream_1D_model
                 downstream_interface = Inflow_2D
            }
            BEDLOAD {
                upstream_interface   = Outflow_upstream_1D_model_sed
                d ownstream_interface = Inflow_2D_sed
             }
        }
        COUPLING {
            type                 = sequential
            upstream_subdomain   = 2D_model
            downstream_subdomain = downstream_1D_model
            HYDRAULICS {
                upstream_interface   = Outflow_2D
                downstream_interface = inflow_downstream_1D_model
            }
            BEDLOAD {
                upstream_interface   = Outflow_2D_sed
                downstream_interface = inflow_downstream_1D_model_sed
            }
