#include "petscts.h" PetscErrorCode TSComputeIFunction(TS ts,PetscReal t,Vec U,Vec Udot,Vec Y,PetscBool imex)Collective on TS
|ts||- the TS context|
|t||- current time|
|U||- state vector|
|Udot||- time derivative of state vector|
|imex||- flag indicates if the method is IMEX so that the RHSFunction should be kept separate|
|Y||- right hand side|
If the user did did not write their equations in implicit form, this function recasts them in implicit form.
