Dear all,
I'm using a DG discretization to solve different kinds of wave equations
in time domain.
I would like to use faster assembly for these systems. Garth suggested
using
parameters['form_compiler']['representation'] = 'tensor'
in stead of the default
parameters['form_compiler']['representation'] = 'quadrature'
Unfortunatly the tensor representation appears not to support Facet Normals:
"ffc.tensor.monomialextraction.MonomialException: No handler defined for
terminal FacetNormal."
I would be happy to invest some time in adding the necessary code to
make this possible (since I really need the speed-up),
is there anyone who could get me started (Give a rough idea of what has
to be done, and what scripts I should look at)?
Thanks in advance,
Steven
P.s. I have some experience with making adjustments to dolfin
