Course Outline:

For advanced RADIOSS users, we offer a RADIOSS Fluid Structure Interaction training, which deals with modeling (ALE, SPH) and computation of fluids and their structural interaction. The following topics are covered: Drop tests of fully and partially filled containers, tank sloshing, ditching, bird strike, shock absorbers (viscosity) and explosions.
