Parametrer Optistruct in order to obtain a frame design

Altair Forum User

Dear all,

 

I am actually working on a tubular chassis optimization and I am a beginner HW.

I would like to obtain this kind of result : 

 

And actually my result (for only one load case in torsion ) look like : <?xml version="1.0" encoding="UTF-8"?>

 

So my question is how to parameter Optistruct in order to obtain a result like a frame ?

 

Thanks,

 

Alban

Hi Alban,

 

The structure you see depends on the loads, Bcs, manufacturing conditions etc...

 

Try with a static frontal load instead of torsion and check if you see any such pattern. 

 

Here is a sTInpisre report for a similar case:

Hi Prakash,

 

Thank you for the advise, I will try different conditions today.
