My model includes several sheet metal parts. I adjusted the element sizes so that the mesh quality appears acceptable.

However, when I try to solve the model, I receive the following error message:

“Check of the simulation model failed. This model contains silver elements. The analysis cannot be performed.”

I have checked the model multiple times and even recreated it from scratch, but I continue to receive the same message. Similar models have been solved successfully in the past without any issues.

I cannot find any explanation of what “silver elements” means, nor can I identify where these elements are located so I can correct them. I also could not find any relevant information in the Help Topics or online resources.

Does anyone know what this error refers to or how to resolve it?
