With this usage, it fails for us, probably because we are mispecifying the options. The following code tries to solve it first using the solve() command, then with LinearVariationalSolver.

I changed the keyword arg names in linearvariationalsolver (and the nonlinear equivalent) to be the same as solve. Hence you need to use solver_parameters=... In both cases. Sorry for the confusion. Is this wrong in the docs?
