Hi, I am working on a linear elastic problem and need to work with PEERS element. I am not sure whether it is possible to do it with FEniCs. I found the following thread, which seems to be a work around. But the thread is bit simple and I could not get it work.
B = VectorFunctionSpace(mesh, "Bubble", 3) _H = VectorFunctionSpace(mesh, 'RT', 1) H = _H+curl(B)
I did the above, but get error at H = _H+curl(B). Is there anyone could give me some help on this?
Another alternative is to use AW element. I am also not sure how to implement that with FEniCs. I found the following old thread.
I’m not sure is there anyone has worked on it. I need to work it out, so if someone could guide me in terms of coding, I am willing to spend some time to contribute to this.
