Hello,

I was wondering if Pylith allows model boundaries that are oblique to the x,y,z axes. I am trying to reproduce a “piece of cake” model (to mimic axisymmetric conditions) but I get the error “RuntimeError: Invalid null space vector 0 has zero norm.”

If I comment the lines where I block the [0,1] degrees of freedom of the two oblique boundaries, Pylith runs without error, but the solution is not the one I am looking for.

Thanks,

Laura
