We actually considered implementing these months ago when we were playing around with the shallow water equations. There shouldn't be any obstacles to P1NC triangles on uniform grids, but we decided not to code them up when we couldn't figure out what the right thing to do on hanging nodes would be. The geometric Elem to use will be the TRI6; just tell the thing you've got one DOF per side node and zero per vertex. The only remaining catch is that code which makes assumptions of C0+ continuity won't work. This includes the penalty boundary conditions in our example problems. --- Roy > Note: Forwarded message from Brian Carnes below... > > Derek > > On Jan 1, 2008 11:01 AM, B C <[EMAIL PROTECTED]> wrote: >> Derek, >> >> Been doing some more libmesh coding I got a crazy idea to put a >> nonconforming tri3 element into libmesh.
