ESLM OPTIMIZATION FOR A CRASH MODEL

Recommended Posts

Hello,

I want to optimize my small sample model of hexas just to test the optimization and the esl method.I wan to use 4 static loadcases and one crash case for the optimization.

I have finished with the 4 static loadcases but i have an issue with the crash case.

I have created the model in optistruct and i dont know how to finish the setup of that case.

More over i cant understand how the Radioss is executed in optistruct optimization for the expdyn?

can you please answer that questions ?I  am trying for more than 2-3 weeks...

Thank in advance Mick Mallow
