 Function to evaluate nonlinear residual

Synopsis

#include "petscts.h"  
PetscErrorCode  SNESTSFormFunction(SNES snes,Vec U,Vec F,void *ctx)
Logically Collective on SNES

Input Parameter

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

Notes

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().
