I don't think so. We used to be compatible (on quad/hex only meshes) with deal.II, but that might not be the case anymore. > Also, I do have non lagrangian elements with DG in my computation. Does XDR > class handle this ? The XDR format should handle every combination of libMesh geometric elements, finite elements, and polynomial degrees. It's basically our custom format. "XDR" is just a lower level standard; saying that our output is "XDR" is like calling an HTML file "ASCII". For first order DG elements (and quadratic Tets, it seems), the VTKIO class writes out enough information to enable a proper restart... and it looks like it's writing out added vectors, too. I'd want to test the code before relying on it, though; IIRC it was only last year that I fixed the GMV output code to properly write in double precision. And for cubics or more exotic elements, writing out .xdr (or .xda, or some gzipped or bzipped version of either) is the only option. --- roy ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
