Pre-processing tools must be used to prepare models for Radioss. Altair Simulation provides specialized pre-processors interfacing with the solvers.

HyperMesh can be used to mesh and set up finite element simulations by selecting the Radioss user profile. There are specific tools that can be used to create Radioss models for Crash and Safety; dummy positioning, seat mechanism, pre-simulation seat deformer, seatbelt routing, pedestrian impact, and head impact.

HyperCrash can also be used to set up finite element models for automotive crash simulation in Radioss.
