Interesting. I can see about adding you to the list, if you want?

I have some code which uses SUPG but it's not simple enough to be an example. Nothing using simple upwinding though. Was this in 1D, 2D, 3D? Maybe the dealII example could be co-opted to work in libmesh? -- John ------------------------------------------------------------------------- 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-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-devel
