Element grouping and group optimization

Altair Forum User

Hello,

I want to create a concrete beam with manufacturing constraints. I have to collect elements (for example 5*5*5 elements) in groups. After that, these (element-)groups should be optimized as a whole. 

You can imagine the manufacturing as a 3D concrete-printer which is only able to 'print' a layer which matches to one (element)group. So the whole beam should consist of

these layers=element-groups. 

Is it possible to do it with a topology optimization?

 

Thanks for your help,

Fabi

Hi,

 

Yeah, you can create a group of elements and make this group as a design space where optimization is only carried on these elements and rest of the elements are untouched.
