Create Boundary Condition in Polygonal Region

General

In order to create boundary conditions in a polygonal region the following workflow can be used:

  1. Extract surface using ExtractSurface (a: Original subsurface mesh; b: Extracted surface)

    Sub-surface mesh
    Sub-surface mesh

    Extracted surface
    Extracted surface

  2. Mark the mesh elements within the polygonal region deploying the tool ResetPropertiesInPolygonalRegions

    Surface and polygon

    Marked elements in polygonal region are colored yellow

    Marked regions visualized by different colors

  3. Remove marked/unmarked mesh elements deploying tool removeMeshElements

    Resulting patches visualized by different colors and z-translations

  4. Compute the associated area for the nodes of the surface mesh deploying tool ComputeNodeAreasFromSurfaceMesh

The surface mesh patches (created until step 3) can be used as input for OGS-6 simulations. For OGS-5 simulations only the additional step 4 has to be performed.
