Abstract : Robust and accurate schemes for various 1-D hyperbolized dissipative systems with stiff source terms were developed and tested with success. A Euler preconditioning matrix that maintains the largest possible angle between the eigenvectors of the preconditioned system for the entire Mach number range, was developed in order to prevent the observed stagnation point instability, and tested with success. A Navier Stokes preconditioning matrix that restrains stable and effective for all Mach numbers and Reynolds numbers was developed and tested with success.
