Preconditioner used in NonlinearVariatiaonalSolver solving mixed formulation
4 months ago by
I'm writing a script to solve a SUPG stabilized Navier-Stokes equation, which results in solving a 2x2 block matrix. So far the NonlinaerVariationalSolver works very well with my problems, and seems to be well scalable. I'm wondering what kind of preconditioner is by default employed in such context (also what choice that I have for parallel), because when I query the information of the solver by calling info(solver.parameters, True), I only get "default" on the value column, and "Not set" on the range column.
