Lattice Type 4 Failing with 0 Compliance

Hi @Tom Barnes

Please try this file,

Still achieve the same result with 0 compliance

Hi,

I am able to run the file as it is. But after looking at the results, I see that there is no load is going to the structure.

Please check and correct the same.

If you are referring to the 4_bending_lattice file I also see the same. I believe this could be because the lattice type used results in the nodes where the force being removed? Is this correct?

Can anybody help with this? I am still having the same problem after trying multiple solutions?

Looks like it is. Try apply loads on element nodes and check if that helps. You may face another error with contacts.

If you face any issue with contacts after applying loads on element nodes, please let me know.

Hi Prakash,

The loads are already applied to the element nodes with the same problem

Hi,

OK, let me have a look at your previous model and I will get back to you.

Hı @Prakash Pagadala and @Tom Barnes

If you could solve the problem, can you say it to me?

Thank you

Hi @Tom Barnes and @Busra ASlan

Sorry that I missed this forum post.

I tried connecting the load to the nearest nodes and I am able to see results.

It is recommended to make the elements connected to spcs and loads part of non-design space.

I see Thank you @Prakash Pagadala

I tried to do as you say. I applied to the non design region load and constraint. but I get an error.

Can you share the error, please?

I ran the file as it is and I didn't face any road blocks

Of course @Prakash Pagadala

@Busra ASlan

Looks like you have contacts in your model.

You can edit the .fem file in any text editor and go to line 7542 which contains contact details.

remove the .F from the line shown in the error message, save the file and try again.

I am sorry@Prakash Pagadala

I checked all the .fem files in a text editor, but I could not find that line.please, Could you show me?

Hi @Busra ASlan

Search for N2S after opening the .fem file in text editor and delete the .F on the same line,
