TSComputeRHSFunctionLinear#

Evaluate the right hand side via the user-provided Jacobian, for linear problems Udot = A U only

Synopsis#

#include "petscts.h"  
PetscErrorCode TSComputeRHSFunctionLinear(TS ts, PetscReal t, Vec U, Vec F, void *ctx)

Collective

Input Parameters#

  • ts - time stepping context

  • t - time at which to evaluate

  • U - state at which to evaluate

  • ctx - context

Output Parameter#

  • F - right hand side

Note#

This function is intended to be passed to TSSetRHSFunction() to evaluate the right hand side for linear problems. The matrix (and optionally the evaluation context) should be passed to TSSetRHSJacobian().
