Results from optistruct are the same as the input geometry

Altair Forum User

I am attempting to optimize an imported geometry though I ran into several problems;

 

- The mesh quality was apparently lacking (used the tetra mesh option to mesh create it), so I bypassed this check by using a control card.

 

- Though point loads and contraints have been applied to the mesh, the output is only of a few iterations and too closely resembles the geometry to be called a viable optimization: reducing the upper bound of the optimization constraints does not appear to resolve this...

 

As a side note, I would also like to know if it would be possible to implement moments onto the mesh. I have a general idea but I'm not entirely sure.

 

I will attach supplementary files as soon as I am able.

 

Thanks

 

Edit: I would also like to mention my goal is to minimise compliance with a volumefraction or mass fraction as an optimization constraint.

 

Edit2: Nevermind I solved my own problem.

Hi Umar,

 

Did you try iSO contour on HyperView?

 

Does it show same contour through out the model?

 

Can you share the .out file and also model file using file transfer link available in my signature below?
