Free surface writes geometries

[jginternational]

Free surface fails running because of this:

In the first picture we can see the the group Fluid:

In the second picture we can see the group Surface bottom:

They do share elements

In the MDPA, both groups are written as Begin Geometries Triangle2D3 So there are elements declared 2 times, with the same id and the same connectivities. This should not be a problem, but it is.

You can see the log:

  File "C:\Users\garat\Desktop\Deploy_Kratos\Deploy_Kratos\KratosMultiphysics\analysis_stage.py", line 80, in Initialize
    self._ModelersSetupModelPart()
  File "C:\Users\garat\Desktop\Deploy_Kratos\Deploy_Kratos\KratosMultiphysics\analysis_stage.py", line 285, in _ModelersSetupModelPart
    modeler.SetupModelPart()

in kratos/includes/model_part.h:1538: ModelPart::AddGeometries
   kratos/includes/model_part.h:1560: ModelPart::AddGeometries
   kratos/sources/model_part_io.cpp:1771: ModelPartIO::ReadGeometriesBlock
   kratos/sources/model_part_io.cpp:618: ModelPartIO::ReadModelPart

Then in the submodelparts definition, each group references it's triangles.
