Unexpected Termination of Run

[meldoone]

Hello,

When trying to solve the "TIMES_TUTORIAL" and "TIAM_WORLD" models I receive a message: "Unexpected Termination of Run".

When solving "TIMES_DEMO" everything is ok.

Can someone help me to solve this problem.

Probably I need to post some logs of this problem. I can certainly do that if someone tells me where to find these logs (GAMS directory, WrkTIMES directory, ...)?

P.S.: directory "..\VEDA\VEDA_Models\TIMES_TUTORIAL\Logs\" is empty.

Post the file <run name>.LST from the gams_wrk folder.

Let me see...

Oh, found it. So I guess it is the log of the model run:

 uploads/93/BASE.lst.txt

uploads/93/QA_CHECK.LOG.txt

P.S.: Thanks for the advice to attach files.

We need for Antti to see this...

post the file C:\VEDA\Veda_FE\GAMS_WRKTIMES\QA_CHECK.LOG in the mean time. you can attach the file instead of copying it. It would be good if you edited your previous post to this effect.

Well, the error indicates that you have either defined a zero discount rate (G_DRATE), or no discount rate at all (most probably no discount rate at all, because using explicit zero should work in v3.2.0).  Can you check whether that is the case? Specifying a discount rate for all internal regions is mandatory in TIMES.

If checking that does not resolve the issue, I would need to have all the DD files and the RUN file, in order to reproduce the problem by myself and investigate the cause.

Anyway, I find it strange that such a problem would appear when running the Tutorial model.
Amit: Can you confirm that the Tutorial model has such an issue?  If so, the model should be corrected.
BTW: Is the Tutorial model available for download somewhere?

[AKanudia]

Thanks Antti.

The tutorial model is a part of the getting started package.

This model is used in training activities, so it should not have this deficiency. Mauri can (should!) confirm.

Thanks Amit.

Actually, I can see from the listing file that indeed G_DRATE has not been specified at all: The parameter has no instances. However, looking at the Tutorial model, I can see that "Discount" has been defined in SysSettings. I guess "Discount" is an alias for G_DRATE? If so, something strange is going on: How come is the G_DRATE parameter being left undefined, even though it has been defined in SysSettings?

Whatever the reason is for this mystery, I think I will add a new QA check for the discount rates, so that the user would be able to see a message in the QA_Check.log as well.

I think I have understood the reason.

By default when opening TIMES_DEMO in the Case manager I have SysSettings checked in the Scenarious field and I have SysSettings NOT checked by default when opening TIMES_TUTORIAL in the Scenarious field in the Case manager.

The thing is that when you are the new user you are trying to learn VEDA and solving the model leaving unknown fields unchanged by default.

When I check all the scenario fields (including SysSettings) the model gives me an optimal solution.

Thanks for the help about the log files: it is very useful to know what are the main logs.

My possible advice is to make the tutorial models able to be solved using the default VEDA options.

[AKanudia]

Good.

So, the basic conclusion here is that you MUST select the SysSettings "scenario" in all runs.

[meldoone]

Yes for sure.

Want to thank AKanudia and Antti-L for the assistance.
