Empty file for the results

Hi,

I've done simulation only with hydraulic (v3.0). Everything is working fine.

Problem1:
After this great work, I have try to add the morphodynamic simulation. I have try the setup (which works) and run the simulation. The simulation duration is 3seconds (that's really really fast) and the xdmf file is empty when I load it in Paraview. Do you have some idea where could be my error? I have used the tutorial to compare.

Problem2:
Can you explain why we have to use the curvature parameter? If we don't add it, the setup doesn't works.

Quentin

Hi Quentin

I suspect that you have a problem with the model setup. The Curvature block is not a mandatory block, so the model should work without it.

Here is an example how the Morphology block could look like:

                "MORPHOLOGY": {
                    "INITIAL":{
                        "type": "mesh"
                    },
                    "PARAMETER": {
                        "morphodynamic_start": 10.0,
                        "sediment_porosity": 0.4,
                        "sediment_density" : 2650.0
                    },
                    "BEDMATERIAL": {
                        "GRAIN_CLASS": {
                            "diameters": [0.0025]
                        }
                    },
                    "BEDLOAD": {
                        "FORMULA": {
                            "type": "MPM_like",
                            "factor": 1.0,
                            "coefficient":4.0,
                            "exponent":1.6,
                            "critical_value":0.047
                        },
                        "BOUNDARY":{
                            "STANDARD": [
                                {
                                    "name": "inflow_MOR",
                                    "string_name": "inflow",
                                    "type": "equilibrium_in",
                                    "reference_bed_elevation": 0.1
                                },
                                {
                                    "name": "outflow_MOR",
                                    "string_name": "outflow",
                                    "type": "equilibrium_out",
                                    "reference_bed_elevation": 0.0
                                }
                            ]
                        }
                    }
                }

Best regards
Matthias
