A System can return a reference to the EquationSystem of which it is a part. system.get_equation_systems(); should do it (see include/solvers/system.h).

I believe Derek's writing nonlinear solvers right now, so he will probably have more to say shortly... -- 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-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
