Hello.
I have created different computational models to evaluate multiple earthquake load scenarios simultaneously. However, not all of these models can run at the same time. I’m getting the following error:
“1. Solution exception: Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection’s state is no longer correct.”
When I recompute in Grasshopper, the models that fail change — meaning there isn’t a specific model that causes the problem, but rather that all of them can’t execute simultaneously.
Dear @fatma2,
sorry for the inconvenience.
Could you post a simplified version of your definition which can be used to reproduce the problem? This would be very helpful for debugging.

Hi, so the error is correct but this is because of an error in the MeshLoad component - however it is not shown in the element itself as theoretically it works.
The reason for the error is that you actually should input text into the ElemIDs and not the elements themselves.
