It seems like your simulation has completed, but Workbench appears to be stuck. This could be due to a variety of reasons, such as post-processing tasks that are still running in the background or a graphical user interface (GUI) issue. Here are a few steps you can take to troubleshoot the issue:

1. Check if there are any post-processing tasks that are still running. Sometimes, even after the simulation is complete, there might be additional calculations or data transfers that need to be finalized.

2. If you suspect it's a GUI issue, try minimizing and then maximizing the Workbench window, or closing and reopening the project to refresh the interface.

3. Ensure that your system meets the hardware requirements for running such simulations, especially in terms of RAM and CPU capabilities. Running large simulations can be resource-intensive, and insufficient hardware might lead to performance issues.

Also, check if this issue is case specific.
