I have been using DOLFIN 2017.2.0 for a long while and it seems I might have to switch to one of the later releases, however, my code breaks when I run it under the later versions. It is kind of hard to tell how much of it breaks, since I will have to fix each part to go on, but here i my first problem:
I used to create a solver
solver = LUSolver('mumps')
which now breaks.
What is/are the equivalent statement(s) in DOLFIN 2018.1.0 and/or 2019.1.0?
