DMDATSIJacobianLocalFn#
A prototype of a local residual evaluation function for use with DMDA that would be passed to DMDATSSetIJacobianLocal()
Synopsis#
#include <petscts.h>
PETSC_EXTERN_TYPEDEF typedef PetscErrorCode(DMDATSIJacobianLocalFn)(DMDALocalInfo *info, PetscReal t, void *x, void *xdot, PetscReal shift, Mat J, Mat B, void *ctx);
Calling Sequence#
info - defines 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 parameterJ - Jacobian matrix
B - matrix from which to construct the preconditioner; often same as
Jctx - optional context
Note#
The deprecated DMDATSIJacobianLocal still works as a replacement for DMDATSIJacobianLocalFn *.
