Using /STATE to initialize elements in Radioss

Radioss offers the capability to store the deformed mesh and its corresponding material state between different simulations. This feature gives an excellent flexibility in multi-stage simulations, such as:

• Considering the manufacturing process into a crash simulation
• Consecutive drop test simulations
• Dummy and seat settling for a crash Loadcase

Some element states that can be recorded are:

• Nodal positions (deformed mesh)
• Element thickness
• Stress and strains
• Temperature
• Fiber orientation

This article includes:

• A presentation showing how /STATE keyword works and how to use it
• An example tensile test model with comparison using and without using /STATE

The Model and Presentation can be downloaded here.
