PetscErrorCode DMDATSSetRHSJacobianLocal(DM dm, DMDATSRHSJacobianLocal func, void *ctx)
Logically Collective
Input Parameters#
dm -
DM
to associate callback withfunc - local RHS Jacobian evaluation routine
ctx - optional context for local jacobian evaluation
Calling sequence of func
#
PetscErrorCode func(DMDALocalInfo *info, PetscReal t, void* x, Mat J, Mat B, void *ctx)
info - defines the subdomain to evaluate the residual on
t - time at which to evaluate residual
x - array of local state information
