I add a new study to a project with several old studies already run. I save the file. When I reopen it I do not find the last added study. Why?
Is the Simulation Add-in still turned on? If yes, does it happen to one specific file, or to every new model that you start simulating?
The simulation Add-in is turned on all the time. I invoke it automatically at the start-up.
I am not sure that this happen to every model. I have not made systematic checks.
As a temporary turn-around I use in this moment save as instead of save, and switching between two different file names at each save.
Unfortunately this works well only when my model is a part. If the model is an assembly difficulties arise with the file dependencies.
Try to do a systematic check, and try it on a different version/system. It could be file-specific.
