Ahh yes. Buit couldn't DofMap::reinit() copy the send_list before distributing new dofs? That is the list we want...

Whoa, wait, take a closer look at my patch. There's two localize calls it was supposed to fix. In the second call, it *uses* the DofMap send_list, because we're synchronizing data on the new, current partition. But in the first call, it *can't* use the DofMap send_list, because where data needs to come from and needs to go ends up having nothing to do with either the old partitioning's ghost nodes or the new partitioning's ghost nodes - it has to do with how the old partitions and new partitions overlap, and to the best of my knowledge we've never constructed a send_list like that before. --- 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
