ERROR #1000 "+EPATH2 0"

I'm trying to perform a topological optimization on a piece.

To do so, I've created a card filling all the requirements in the "Design Variables" section.

In the "Extrusion" section, I've specified "no twist" and have chosen two nodes in the "primary path" that define the direction of the z-axis when combined.

However, every time I run the optimization, I encounter the following error: "Error #1000 "+EPATH2 0"

. I've attempted to use different nodes and tried various selection methods, but I keep receiving the same error.

Does anyone have any suggestions for resolving this issue?

I attached the .fem file

In this model the Primary node path is missing. see the below image. I updated this and now it is running. Attached is the updated file.

this should be filled only if 'twist' was used.

Maybe you could open the .fem file in a text editor, and delete this specific 0 value after EPATH2 and try to run again.

If succeded, then try importing back the .fem into HM to see if it is correct.

I first tried unselecting the nodes on the "primary path" option. It caused an "EPATH1 0" error.

I opened the file with a text editor and deleted the 0. How can I simulate the .fem edited without running it from HyperWorks?

Hi Adria,

It will be easy to debug if you can share the fem file.

I am doubting the error may be due to Node path selection with Twist option.

So please share the file to look into the issue.

Thanks
