I guess I could hack in a feature in SFC to reuse an integral without this cost, but I still think this should be possible to do from within dolfin given an existing UFC form. -- Martin >> and want to assemble a matrix with f being a >> function f0 at subdomain 0 and f1 at subdomain 1. >> Maybe f0 is a discrete function and f1 a user function. >> I don't think this is possible in dolfin today? >> What would be the best way to go about this? >> >> -- >> Martin >> _______________________________________________ >> DOLFIN-dev mailing list >> [email protected] >> http://www.fenics.org/mailman/listinfo/dolfin-dev > > > _______________________________________________ DOLFIN-dev mailing list [email protected] http://www.fenics.org/mailman/listinfo/dolfin-dev
