TSComputeI2Jacobian#
Evaluates the Jacobian of the DAE
Synopsis#
Collective
Input Parameters#
- ts - the - TScontext
- t - current timestep 
- U - state vector 
- V - time derivative of state vector 
- A - second time derivative of state vector 
- shiftV - shift to apply, see note below 
- shiftA - shift to apply, see note below 
Output Parameters#
- J - Jacobian matrix 
- P - optional preconditioning matrix 
Notes#
If F(t,U,V,A)=0 is the DAE, the required Jacobian is
dF/dU + shiftVdF/dV + shiftAdF/dA
Most users should not need to explicitly call this routine, as it is used internally within the nonlinear solvers.
