I'm afraid not. The NodeConstraints currently have the same limitation as the DofConstraints: they only support constraints with no offset values. That's fine for the periodic BCs on function values, u(left) = u(right), but it doesn't work for the periodic nodal coordinates x(left) = x(right) + offset_value. The initial target for NodeConstraints is moving mesh code, but just for hanging nodes, not periodic node displacements. --- Roy ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
