Is there are technical > reason for this? It has been like this for about a year (since the UFL introduction last year). Before we had the quadrature option, we stretched the tensor representation to support things it really couldn't handle like division, sqrt etc by some tricks. When we did the UFL conversion last year, I thought it best to remove these special tricks to keep the implementation simple. FacetNormal is somewhere in between. It could be added with some effort but since it is handled nicely by the quadrature representation it is not a high priority to add back. > or Division which is known. > > > Without the -r representation > > option, FFC will automatically discover that the integrand in question > > needs to be done with quadrature > > OK, it's good it if can figure this out. Here's how FFC selects the representation: 1. If there's a quadrature element --> return "quadrature" 2. If tensor representation is not possible --> return "quadrature" 3. Compare estimated cost of tensor and quadrature representation and use the most efficient option. The above case gets quadrature because of 2. The cost is estimated as the rank of the geometry tensor (number of derivatives + number of coefficients) and tensor representation is used if the cost is 3 or less. This can be fine-tuned with some appropriate benchmarks. -- Anders > Garth > > > but if someone insists on -r tensor, > > then FFC will try and explain why it fails: > > > > *** FFC: No handler defined for expression Division. > > > > I'll switch the demo back to "auto". > > > >> modified: > >> demo/pde/dg/poisson/python/demo.py > >> > >> > > > >> === modified file 'demo/pde/dg/poisson/python/demo.py' > >> --- demo/pde/dg/poisson/python/demo.py 2010-01-27 21:09:29 + > >> +++ demo/pde/dg/poisson/python/demo.py 2010-02-02 23:16:44 + > >> @@ -23,6 +23,8 @@ > >> > >> from dolfin import * > >> > >> +parameters["form_compiler"]["representation"] = "tensor" > >> + > >> # Create mesh and define function space > >> mesh = UnitSquare(24, 24) > >> V = FunctionSpace(mesh, "DG", 1) > >> > > > > > > > > > > ___ > > Mailing list: https://launchpad.net/~dolfin > > Post to : dol...@lists.launchpad.net > > Unsubscribe : https://launchpad.net/~dolfin > > More help : https://help.launchpad.net/ListHelp > > signature.asc Description: Digital signature ___ Mailing list: https://launchpad.net/~ffc Post to : ffc@lists.launchpad.net Unsubscribe : https://launchpad.net/~ffc More help : https://help.launchpad.net/ListHelp

Great. I think we should try to finish up a release of FFC 0.9.1 before the end of February. Ideally, we should go through all the code again and remove all FIXMEs.

Yes, I noticed that I was still getting errors, but good that you fixed it. I'm cleaning up the parts of the code I've been working on the most including some of the code in cpp.py. Great. I think we should try to finish up a release of FFC 0.9.1 before the end of February. Ideally, we should go through all the code again and remove all FIXMEs. Then FFC will be in ridiculously good shape. Agree, I think that it sounds like a good idea.
