The LS-DYNA ALE formulation allows LS-DYNA to model the fluid filling of a casting. The benchmark problem selected comes from the 7th Conference on Modeling of Casting, Welding, and Advanced Solidification Process, London, England, 10-15 September, 1995. The conference proceedings define a benchmark test for analysis codes. The benchmark test fully defines the problem and presents experimental results including X-ray video of the mold filling. Eight different analysis codes were compared in their prediction of the process...CASTING MODELING (PDF FILE 212KB)

Thermal analysis is used in many fields including the design of heat sinks and other components of cooling systems for stereo systems, televisions and computers. Other uses of thermal analysis and coupled thermal-fluid analysis is in the design of home heating and cooling systems. Medical researchers working in the field of hyperthermia are using heat transfer to treat cancer. Thermal analysis with radiation transport was used in the design of the tiles covering the lower surface of the Space Shuttle to withstand re-entry. Nuclear fuel shipment containers are designed using thermal analysis to analyze and design the container to withstand the heat generated by the fuel.

Simulation codes which offer thermal analysis coupled with structural analysis are able to simulate several challenging manufacturing processes which could not be otherwise handled (e.g., extrusion, forging):
