TSI2FunctionFn#

A prototype of a TS implicit function evaluation function for 2nd order systems that would be passed to TSSetI2Function()

Synopsis#

#include <petscts.h> 
PETSC_EXTERN_TYPEDEF typedef PetscErrorCode(TSI2FunctionFn)(TS ts, PetscReal t, Vec U, Vec U_t, Vec U_tt, 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
U_tt - second time derivative of state vector
F - function vector
ctx - [optional] user-defined context for matrix evaluation routine (may be NULL)

Note#

The deprecated TSI2Function still works as a replacement for TSI2FunctionFn *.
