Lattice Structure Type

Aslan_20882

Hı I am trying lattice structure optimizatons. Actually I can do it.

I want to change lattice types such as 1,2,3,4 and than results compare but I dont have any difference. 

If you know solution for this problem,can you help me?

Thank you

Hi @Busra ASlan

 

So you are changing the lattice type from 1 to 4. But you don't see any change in results...

 

Is it in structure or FE results you don't see any change?

Thanks @Prakash Pagadala

 

Actually I want to see in FE results, but also  if it is possible  I want to see in structure

Hi,

 

I ran a sample model, I can see changes in structure.

Thank you for helping.

I am sharing my files for type 1,2,3,4. I think I made a mistake but I did not find it.

Maybe you can help me.

thank you. 

 

I will check and update you soon. Since you are interested in the results, I will try to post the results ASAP!!

HI,

 

I tried on a test model and I see the difference in structure and results as well. But this is not happening in your case and the reason I think is of the design envelope.

 

I will write to Dev team about this for a better explanation. I am attaching a PPT with my test model.

Thank you @Prakash Pagadala

 I will be waiting for your news. I hope so, my model results can be similar to your model

Hı @Prakash Pagadala,

 

Did you find a solution to my problem with Dev team?

Hi,

 

Yeah, so tetra elements take only one type. Whereas Hexa elements are compatible for all types of the lattice.

Thank you @Prakash Pagadala

 

I tried to make a hexa element using 3D-solid-map for mesh structure. And then I got a solution for 1,2,3 types but  the analysis results are zero for 4 is a solution.

Can you help me?

Can you share the .out file for the type 4 lattice optimization?

Of course @Prakash Pagadala

Hi @Busra ASlan

 

Looks like after optimization loads are not connected to any elements. Can you please check the same and update the loads?
