This manual describes how to use the local linear stability code LSH and the nonlinear Parabolized Stability Equations PSE solver PSH for compressible flows. Both codes are adaptable to analysis of different flows over fairly general shapes of bodies. For analysis of a new problem, the user may specify the basic state, the coordinate system, dependent disturbance variables and their boundary conditions to be used for the stability analysis through physics insert files. Once these preliminary steps are completed, different tasks of stability analysis and PSE calculations can be carried out by simple modifications of a few input files. Both codes are highly modular and closely integrated. Output data from LSH can be used directly as initial data for PSH runs. Examples of several insert files and input files of the built-in problems are given to assist the user in setting up a new problem.
