Type of Lattice structure

Aslan_20882

Hı,

I'm doing lattice structural optimizations. Lattice type 1 and 3 is working but 2 and 4 are not working. I get this error.

Can you help me?

Thank you.

Hi,

can you share the entire .out file, please?

Aslan_20882

Of course @Prakash Pagadala

lattice type 4 is used in this file. The solution is working when using lattice type 1 and 3 with the same parameters.

Hı @Prakash Pagadala,

I understand what is a mistake. But I can't run when I try myself on the first model. Which did you change parameter?

Hi @Busra ASlan

I didn't change anything related to optimization. But I removed the badly formatted line on the CONTACT card.

Hı @Prakash Pagadala,

Thank you for your answer,

But I don't understand. How can I remove the badly formatted line on the CONTACT card?

I am sorry, can you tell me more clearly.
