| snes | - the SNES object | |
| dm | - the DM | |
| u | - a DM vector | |
| exactFuncs | - pointwise functions of the exact solution for each field | |
| ctxs | - contexts for the functions | |
| tol | - A tolerance for the check, or -1 to print the results instead | |
| error | - An array which holds the discretization error in each field, or NULL |
