Lattice Optimization Not Solved
Hı everyone,
We are trying to do lattice optimization with different types.
We tried every way, we thought. And we get different errors every time. Finally we have made the hexa mesh using another program. And then solved in Optistruct. Although there is no problem in the solution, the lattice.fem file does not occur.
Could you help me?
Thank you.

I don't see any problem in the .out file.
After analysis do you see any .fem file written in the working directory?

Hi @Aslan
I ran some cases with different types of lattice and the rest of the parameters intact.
I didn't see any change in most of the cases except in the lattice design.
I am waiting for experts feedback and what is happening in the background.

Yes I tried. But this is a different topic.
The file, you share with me about another topic.

Sorry, I am little confused with threads.
Anyways, I see that the simulation didn't run completely as there are restarts files in the folder.
Can you let me know which pre-processor is used for meshing (you mentioned. Finally we have made the hexa mesh using another program)?
If possible, please share the file.

Did you try the file, I shared with you?
I have tried for topology and solved.
But, for lattice optimization don't solve.
Maybe due to my version.
Could you solve it with your program? I wonder, it will be solved or not.
Thank you.

Hi,
I am got the files, I will check and update you soon.

Hi @Aslan
I see a similar behavior as you have. How about reducing the design space to get a completeness?

Add some of the elements from design space to non-design space, especially where the continuity is losing.
