TSI2JacobianFn#
A prototype of a TS implicit Jacobian evaluation function for 2nd order systems that would be passed to TSSetI2Jacobian()
Synopsis#
Calling Sequence#
- 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 
- v - shift for U_t 
- a - shift for U_tt 
- J - Jacobian of G(U) = F(t,U,W+vU,W’+aU), equivalent to dF/dU + vdF/dU_t + adF/dU_tt 
- jac - matrix from which to construct the preconditioner, may be same as - J
- ctx - [optional] user-defined context for matrix evaluation routine 
Note#
The deprecated TSI2Jacobian still works as a replacement for TSI2JacobianFn *.
