parametric optimization


Has anyone done parametric optimization in optistruct-hyperstudy?
i want to do that crossbar can slide through frame. I defined morph volume. But i don't know how can i connect desvar and morph volume?
Is it right way? i have seen just size/shape configuration, so it's not my way.
i had tryed to save volume and looked for txt file. it doesn't consist elements, so i can't use it in hyperstudy.
could anyone explain me how does it works?=)
Thanks.

First create desired shape using morphing (Morph volume/domain handle approach).Once the morphing is done, you can export shape variable from Hypermesh to HyperStudy.Refer HS-1021 and HS-1025 Tutorial.

@Rahul R i understand, but issue is in creating shape.
i created morph volume. and how to create shape from volume?

You can refer HyperMesh Morphing Tutorials for Morph Volume concept.
HM-3550: Morph Volume

ok.
But how does it help me to create 'shape' for assigning desvar? i don't understand you @Rahul R. i'm just newbie in Altair Software.

i did it, but i should move it. if i do not move it shape will not be saved. it was my problem. i had moved it to 0.001 mm and saved.
thanks.

Can you share the .hm or fem file to have a look ?

ok. but not now. thank you for your help offer. Can i take it latter? i try to do optimization model. if i have some complications with it i will send model to you, ok?

I’m interesting in 2 moment now:
1. How to interpret this moment
but as you can see in result:
I think it’s not 10 mm…=)
2. I want to do model that aim will be frame stiffness. So I am just solving 3 case of solution. But I want to solve 10,20,30… etc, and HyperStudy should look at SPCF MX at grid 479017. I don’t know how does it realize? It is very interesting work for me. I try to vary crossbar position and it thickness.

It would be nice if you can share .xml or .hstx file of HyperStudy to take a quick look.You can use dropbox available in my signature.

is it that?

i hope i fix it.
i haven't solved question about crossbar displacement. (how to define displacement of crossbar, if i assign for down boundes(-10), initial(0) and upper bound(10) it will look larger)
and i want another approach. i do sweep, but it grows linear my values. could you give me advice, @Rahul R?

For bound you have option to change the value as per your requirement.Refer below post.

Thanks for the good ideas to bring it. I know a lot more.
