PetscErrorCode DMProjectFunctionLocal(DM dm, PetscReal time, PetscErrorCode (**funcs)(PetscInt, PetscReal, const PetscReal [], PetscInt, PetscScalar *, void *), void **ctxs, InsertMode mode, Vec localX)
Not collective
Input Parameters
|  | dm | - The DM | 
|  | time | - The time | 
|  | funcs | - The coordinate functions to evaluate, one per field | 
|  | ctxs | - Optional array of contexts to pass to each coordinate function.  ctxs itself may be null. | 
|  | mode | - The insertion mode for values | 
Output Parameter
Calling sequence of func
   func(PetscInt dim, PetscReal time, const PetscReal x[], PetscInt Nf, PetscScalar u[], void *ctx);
|  | dim | - The spatial dimension | 
|  | x | - The coordinates | 
|  | Nf | - The number of fields | 
|  | u | - The output field values |
