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().
