In order to select to keep the cells in multiple disconnected regions it is
necessary to specify a location in each of those regions as a list of points,
e.g.
castellatedMeshControls
{
.
.
.
locationsInMesh
(
(-0.18 0.003 0.05 )
(-0.09 0.003 0.05)
(0.09 0.003 0.05)
(0.18 0.003 0.05)
);
.
.
.
}
The locationInMesh control is still available for backward compatibility and to
specify a point when meshing a single region.
