It is indeed demo/function/projection-interpolation/python, see http://fenics.org:8010/dolfin/linux_64/builds/1212/step-test/0 and http://fenics.org:8010/dolfin/linux_64/builds/1212/step-test/1 ilmar _______________________________________________ DOLFIN-dev mailing list [email protected] http://www.fenics.org/mailman/listinfo/dolfin-dev
