We don't do anything particularly controversial with our Eigen wrappers, for example the EigenSparseLinearSolver does not even appear to have any "state" which could get messed up between solves. So I think it's likely that the error is in Eigen itself and you'll need to get help from those devs, who will likely want an Eigen-only example. Of course, now that I've said that, we'll probably figure out that it's our fault somehow :_[ -- John _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
