Hi Timo Quoting Timo Koellner <[email protected]>:
I now attempted to transform the problem to a second order problem. Here I expierence another problem. When applying the gradient to the first order equations I get a delta function in the right hand side. How can this be treated in assembling the system?
I think VectorTools::create_point_source_vector is your friend here.
