Automatic Generation of Thousands of Linear Loadcase Combinations for Efficient OptiStruct Static Simulations and Post-treatment with HyperView

Presentation by Samuel Ducarouge, Mechanical Engineer at Air Liquide.

During Cryogenics Pipes mechanical analysis (Liquid Oxygen, Hydrogen or Helium transport) automatic generation of load case combinations has been needed in order to avoid error from "hand made" combinations, to gear up the results analysis by simplification of data combination in HyperView (time to display results has been reduced drastically) and to avoid conservatism by simplification of the combinations.

This presentation deals with pre- treatment and calcul in OptiStruct of the unitary load cases as well as load case combinations creation and calculation by using special tool developed by Altair.
