To be clear, this is a feature of the FEMContext object, itself a part of the FEMSystem family of classes. An example of FEMSystem use is ex18, "plain vanilla" libmesh doesn't have these functions. -- John ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
