FOQUS UI/Cloud: No Aspen License Error

[boverhof]

Description

If the Aspen license can't be checked out when using the FOQUS Cloud the user gets back an unhelpful message.

This issue seems to be old and still exist.

I was runnig FOQUS in PSE server (not FOQUS cloud), there were cases when we run ensemble in uncertainty tab, the license check failed and the ensemble didn't stop. It continuesly running the next case until all cases failed. It would be nice to stop the ensemble automatically once it triggeled the license check failure in Aspen plus and also provide messages to inform that this stop was triggled by license check failure. In current version, due to lack of detailed failure message for the ensemble, we are assuming that the failure was due to Aspen Plus convergence failure.

@Lingyan90, thank you for this. Could you give us details, pointers to specific files, etc. on how to reproduce this?

[Lingyan90]

@ksbeattie to reproduce this may need to intensionly deactivate the aspen license. I can try that on my PSE server tomorrow to reproduce the issue and could give more details on how to deactivate the aspen license (suppose I can), and provide a simple flash vessel example.

@ksbeattie, I was able to reproduct the issue:

1. Remove all Aspen Plus server from aspenONE_SLM License Manager-->SLM Configuration Wizard-->Remove servers listed under Server Name.
2. Test a already build aspen model to make sure the license test failed.
3. Test in FOQUS ensemble. Use the previous build aspen model, created a node in FOQUS, and in Uncertainty tab, I use LHS generated 20 samples to run the aspen in FOQUS, the samples failed with error message like Failed to check out a license, but the ensemble didn't stop. I manually stoped it at sample 15.
