This manual presents examples solved using Radioss with regard to common problem types.
A 1D shock tube filled with detonation gas products is used as a test model for the JWL equation of state.
The transitory response of a perfect gas in a long tube separated into two parts using a diaphragm is studied. The problem is well-known as the Riemann problem. The numerical results based on the finite element method with the Lagrangian and Eulerian formulations, are compared to the analytical solution.
An expansion wave appears in a supersonic flow as it turns around a convex corner.
A supersonic flow encounters two successive wedges and oblique shock are formed.
A sinusoidal imposed displacement is applied to a hollow sphere to study wave propagation.
