cfMesh hack for 3D OpenFOAM meshes and simulations

This is the entry you need in system/meshDict (don't forget to adopt the boundary names to your boundary names!):
renameBoundary
{
defaultType patch;
newPatchNames
{
inlet1
{
type patch;
newName inlet1;
}
inlet2
{
type patch;
newName inlet2;
}
outlet
{
type patch;
newName outlet;
}
wall
{
type wall;
newName wall;
}
}
}

Great. I did discovered and use this approach for sometime already. Can be use for 2d geometry as well.
