SNESVINEWTONSSLS

 Semi-smooth solver for variational inequalities based on Newton's method

Options Database

-snes_vi_type <ss,rs,rsaug> a semi- smooth solver, a reduced space active set method, and a reduced space active set method that does not eliminate the active constraints from the Jacobian instead augments the Jacobian with additional variables that enforce the constraints
-snes_vi_monitor - prints the number of active constraints at each iteration.
