If you're not using adaptive refinement, I think you can get away with first calling MeshBase::delete_elem() on each of the elements you want deleted, then MeshBase::prepare_for_use() to do some internal cleanup of things like neighbor links, then EquationSystems::reinit() to properly resize vectors. If you're using adaptive refinement, things are harder. I've got a small library patch with changes Victor Velten had to make to get that working correctly for him, but IIRC he didn't get back to me about a couple minor problems, and I never got it into SVN. You might want to check through the mailing list archives on that. --- Roy ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
