Thanks for your reply Garth. I get a seg fault when I run the poisson demo:
~/computer/fenics/dolfin/dolfin/demo/pde/poisson/python$ python demo.py Segmentation fault No other information is given. Any ideas? Should I just forget about the Python interface until someone fixes swig upstream? Thanks, Tim On Mon, Aug 25, 2008 at 3:01 PM, Garth N.
