Using /STATE to initialize elements in Radioss

Guilherme_Brandao

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.
