Preconditioners for hyperbolic systems are numerical
artifacts to accelerate the convergence to a steady state.
In addition, the preconditioner should also be included in the
artificial viscosity or upwinding terms to improve the accuracy
of the steady state solution. For time dependent problems
we use a dual time stepping approach. The preconditioner
affects the convergence rate and the accuracy of the
subiterations within each physical time step. We consider
two types of local preconditioners:
Jacobi and low speed preconditioning.
We can express the algorithm in several sets of variables
while using only the conservation variables for the flux terms.
We compare the effect of these various variable sets
on the efficiency and accuracy of the scheme.
