TopoSet

Valid versions:

topoSet is a utility that collects points, faces and cells in sets, based on different criteria, for later usage with different other utilities like subsetMesh and setSet.

1 Dictionary

The default dictionary is located in

/system/topoSetDict

Usually dictionaries created elsewhere have the extension .topoSet (i.e. myTopoSet.topoSet).

The dictionary looks like:

actions
(
  {
    name    selectedCells;
    type    cellSet;
    action  new;
    source  boxToCell;
    sourceInfo
    {
      box (x0 y0 z0) (x1 y1 z1);
    }
  }
  {
    name    selectedFaces;
    type    faceSet;
    action  new;
    source  patchToFace;
    sourceInfo
    {
      name bottomWall;
    }
  }
);
