ERROR:Unknown assembly set PART-1-1_1 1

Hi everyone, I'm having a problem with the title.

I'm working on a simulation of additive manufacturing.

This is part of the inp file for my job.

When I run the job, it shows Error: Unknown assembly set PART-1-1_1 PART-1-1_2.... .etc

And this is my part.

The set-kill is a three-quarter cylinder.

I'm trying to follow the example, and my understanding is to remove the cylindrical elements first, and then analyze them according to the additive manufacturing printing process.

Then there was a problem, ABAQUS cannot find PART-1-1.1...

Do I need to define set?

If so, is there a quick way to define it?

I did it all according to the example. In his original video, he was making a rectangle, but I made a cylinder instead.

Attached is a sample video, excuse me that this is Chinese.

There’s really no need to use *MODEL CHANGE for additive manufacturing process simulations anymore (not to mention the explicit dynamics step) since there are built-in functionalities for that. There’s even a special AM Modeler plug-in in Abaqus/CAE 2022 and newer. Check the Abaqus documentaion for more information.

Hello FEA way.
Thanks for your reply.
I will try to use AM Modeler.
