I am working with a limited number of licenses. If I try to run a model, while I have another open , I get a license error and then the model seems broke and all I can do is restart and lose unsaved progress. Why would a license error break the model?

I get...

ERROR: There is no solver license!

ERROR: No model has been defined. Check for successful reading of the model before operating on a model.

There are several models and I have seen where I need to View>model to get back to viewing the proper model, but none of that is working in this case.

working with a limited number of tokens is more accurate I suppose

Sorry for asking a stupid question, but you are running the external solver for the solver job, right?

No, solving in View 2021.1

What helps is to check Hold License "no" in executable settings. Wish that was the default.

Still, I don't understand why a license error wrecks the model.

What happens if you try to start your job in the external solver. Do you get a license error then as well?

Thought I'd revisit this topic since it is still happening. No, while running an external batch of jobs, if I open View in the middle of a job and try to solve, I get a license error when the current batch job finishes and tries to start the next. That job errors out, but it queues up and if I close out View, it moves on to the next batch job and solves fine. The View session gets wrecked though as described in the original post.

Actually I didn't answer that question very clearly. Yes, I get a license error when running a job in the external solver without enough tokens, but when tokens are available it continues on with the next file.
