TSIFunctionFn#

A prototype of a TS implicit function evaluation function that would be passed to `TSSetIFunction()

Synopsis#

#include <petscts.h> 
PETSC_EXTERN_TYPEDEF typedef PetscErrorCode(TSIFunctionFn)(TS ts, PetscReal t, Vec U, Vec U_t, Vec F, void *ctx);

Calling Sequence#

  • ts - the TS context obtained from TSCreate()

  • t - time at step/stage being solved

  • U - state vector

  • U_t - time derivative of state vector

  • F - function vector

  • ctx - [optional] user-defined context for function

Note#

The deprecated TSIFunction still works as a replacement for TSIFunctionFn *.
