TSI2Jacobian#
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
Jctx - [optional] user-defined context for matrix evaluation routine
