| dmmg | - the context | |
| function | - the function that defines the nonlinear system | |
| jacobian | - optional function to compute Jacobian |

| -dmmg_jacobian_period <p> | - Indicates how often in the SNES solve the Jacobian is recomputed (on all levels) as suggested by Florin Dobrian if p is -1 then Jacobian is computed only on first SNES iteration (i.e. -1 is equivalent to infinity) |
