Dear all, Just to clarify that the file to execute the test is called "test_assign.py". For ease I've pasted it here: https://gist.github.com/colinjcotter/4b7eb6731a6cb388efee Switching off assembly caching does indeed fix this for me, i.e. parameters['assembly_cache']['enabled'] = False at the top of the file. all the best --cjc ________________________________________ From: firedrake-bounces@imperial.ac.uk [firedrake-bounces@imperial.ac.uk] on behalf of Hiroe Yamazaki [h.yamazaki@imperial.ac.uk] Sent: 25 November 2014 19:03 To: firedrake Subject: [firedrake] .assign() with a function from a mixed function space Dear all, I got confused with .assign() with a function from a mixed function space and I would appreciate some suggestions. The test code is in bitbucket.org/colinjcotter/slicemodels/branch/tidy revision f87e865. I expect a non-zero kinetic energy is printed out in line 54, but the result is still 0. To get an updated kinetic energy, I need line 57. Am I misunderstanding what .assign() and/or .split() do? All the best, Hiroe _______________________________________________ firedrake mailing list firedrake@imperial.ac.uk https://mailman.ic.ac.uk/mailman/listinfo/firedrake
