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())
        );
