Inertia Relief Parameters


Dear Mr. Grassmansdorf,
Thank you for your reply last time. We are making progress in our simulation. Now I have a specific question which is not about the software itself but more about a model problem which I don't know excactly what to do with.
As you know I am making a model about a carbon fiber monocoque. After doing some research I found that I should make use of Inertia Relief Analysis. So I made my constraints with SUPORT1 and got myself a working model. After doing some more research about Inertia Relief Analysis with Altair Hyperworks I stumbled across the controll card PARAM in which you can choose your settings for the Inertia Relief Method.
I noticed quite a big difference in my simulation between these settings. I am sending you this mail because I wanted to know the opinion of an expert in these kind of simulations about what I should do. Can you give me your opinion or maybe tell me if my reasoning is correct?
In the picture below you can see the constraints (suport1) I created for my model.
