SNESTSFormFunction#
Function to evaluate nonlinear residual
Synopsis#
#include "petscts.h"
PetscErrorCode SNESTSFormFunction(SNES snes, Vec U, Vec F, void *ctx)
Logically Collective
Input Parameters#
snes - nonlinear solver
U - the current state at which to evaluate the residual
ctx - user context, must be a TS
Output Parameter#
F - the nonlinear residual
Note#
This function is not normally called by users and is automatically registered with the SNES
used by TS
.
It is most frequently passed to MatFDColoringSetFunction()
.
