Dear All,
First of all, congratulations to the developers of Netgen. I think it is a very good solver and what is more, the documentation is also properly developed which is not that usual.
I'm working on a solver for a system of 3 nonlinear equations. Following the tutorials and documentation, I wrote a Newton solver that solves the problem using a 1D mesh. As some of the parameters in my equations are discontinuous I got into troubles and wanted to implement a DG method to include the discontinuity of the parameters. I followed the DDG tutorial and added the jumps on the boundaries of the elements. In my case that would be points as I am working with 1D mesh.
Unfortunately, during the linearization of the form, I got an error
a.AssembleLinearization(u.vec)
RuntimeError: CalcLinearization for element-wise skeleton-VOL not implementedin AssembleLinearization
Is there anything I can do to overcome this problem or is it just something that is not implemented and won't change?
