Contrib/SplitMeshWithSets

Valid versions:

1 Short description

Splitting a mesh like it is described in Importing a FLUENT mesh with internal walls has problems if it is to be done twice: because the original splitMesh renumbers the faces but the faceSets are not updated it is possible that the information in the faceSets is wrong. This utility updates the sets.

2 Usage

The same as splitMesh. After the mesh was split all faceSets are updated in the following way

the faceSet that was used to split the mesh is erased (set to zero length)
all other faceSets are updated so that the renumbering of the faces is taken into account

another difference to the original behaviour of the original splitMesh is that boundaries with 0 faces are not erased.

3.1 Compilation problems

Some newer non-standard versions of OpenFOAM 1.2 have the problem, that the constructor for attachDetach has changed. Change the call

 
    tm[0] =
        new attachDetach
        (
            "Splitter",
            0,
            pMesh,
            "membraneFaces",
            masterPatch,
            slavePatch,
            scalarField(1, runTime.value())
        );

to

 
    tm[0] =
        new attachDetach
        (
            "Splitter",
            0,
            pMesh.morphEngine(),
            "membraneFaces",
            masterPatch,
            slavePatch,
            scalarField(1, runTime.value())
        );
