PetscErrorCode DMDATSSetIJacobianLocal(DM dm,DMDATSIJacobianLocal func,void *ctx)
Logically Collective
Input Arguments
| dm | - DM to associate callback with
|
| func | - local residual evaluation
|
| ctx | - optional context for local residual evaluation
|
Calling sequence for func
func(DMDALocalInfo* info,PetscReal t,void* x,void *xdot,PetscScalar shift,Mat J,Mat B,void *ctx);
| info | - DMDALocalInfo defining the subdomain to evaluate the residual on
|
| t | - time at which to evaluate the jacobian
|
| x | - array of local state information
|
| xdot | - time derivative at this state
|
| shift | - see TSSetIJacobian() for the meaning of this parameter
|
| J | - Jacobian matrix
|
| B | - preconditioner matrix; often same as J
|
| ctx | - optional context passed above
