Different Lattice Type But Same Analysis Result

Aslan_20882

Hı everyone,

 

I am trying to do lattice optimization with different types.  I'm using hex mesh for design and tetra mesh for non-design. I I can see the different types of lattice in the design structure. But when I check the displacement values, I don't see any difference.

 

Can you help me for this problem?

Hi @Aslan

 

Can you share the model file, please?

Of course @Prakash Pagadala,

I shared it using the https://ftam1.altair.com/filedrop/~Ce4god link.

Thank you.

Hi @Aslan

 

There may be not much change in stiffness, but the lattice structure is different. Did you notice this?

Yes, I noticed. Due to I use different structure ,  the displacement value need to change. is it?

If the stiffness is same then the chances are very less

 

What about with type 1 and type 2, any changes?
