Hi, Yes, it looks like the thing we need, expect that it only works for QUAD4... But I guess I could use it as a model and write a function in my program. If it works we add it to the svn version.
Thanks for all the help. I think I understood the problem and how to fix it. I'll get back with news on the progress and/or more questions cheers Joa On Wed, Oct 14, 2009 at 05:15:26PM -0500, Roy Stogner wrote: > > On Wed, 14 Oct 2009, Derek Gaston wrote: > > >I thought I ran into similar problems when I did mesh redistribution / > >smoothing + adaptivity.
