@Manav: Were you able to run DTK and use it for solution transfer? I tried doing it but I was unable to transfer solutions across meshes. I think dtk for libMesh may be broken. If you get it to work, kindly let me know

If this is currently is not a part of the functionality, is there a quick and dirty way of accomplishing the same? I would greatly appreciate your comments.

Thanks! If you want to chime in or just read my thoughts on the design questions, the issue where I've been documenting them is https://github.com/libMesh/libmesh/issues/1028 The first third of the design got merged in https://github.com/libMesh/libmesh/pull/1057 and I hope to have the next third by the end of the week. This is going to have libmesh_experimental() all over it for a while; I think the design overview is solid but API arguments, return values, etc. aren't set in stone yet. --- Roy ------------------------------ Message: 8 Date: Thu, 11 Aug 2016 05:42:54 -0500 From: Manav Bhatia <[email protected]> Subject: Re: [Libmesh-users] question about distributed mesh To: Roy Stogner <[email protected]> Cc: libmesh-devel <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset=utf-8 Thanks for pointing me to the discussions, Roy. So if I understand correctly, the current implementation of DistributedMesh::add_extra_ghost_elem() only provides the G() version of your new API without an ?evaluable? entity? If my interest is in the E() entity, would it be best to wait for your API, or is there a way to get it to work in current libMesh? Perhaps follow the implementation in MOOSE? -Manav > On Aug 10, 2016, at 6:54 PM, Roy Stogner <[email protected]> wrote: > > > On Wed, 10 Aug 2016, Manav Bhatia wrote: > >> will do.
