parametric optimization

Recommended Posts

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.

Whenever you execute morphing operation using any approach(Domains/Handle,Morph volume or Map to geometry),you have option to save those shape as nodes perturbation.Then you can use those shape as design variable for optimization.

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.

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?

@Rahul R

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.

i have solved particulary second question.

but i had some problem with values. HyperStudy doesn't like it=( Why does it so?

how to fix it?

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?
