Error message

[Anna (AKR)]

Hi,

I have received some strange GAMS error code messages that I don't understand, see below and included file. Anyone that can support?

Good question, Anna!

The partial answer is that you have a GAMS domain violation, which triggers filtering all parameters via a GDX file.  But for some reason that does not seem to work correctly under your GAMS 34.2.0 (I guess this is brand new GAMS).

Therefore, the best solution for you now is to fix the domain violation in your model. It seems the commodity 'BFUKER' has not been defined as a commodity.  I hope you can find that error in your model.

But as for TIMES, the problem with the latest GAMS, causing the unexpected error, should also be fixed. I will try to see if I can find out why this error arises...  I have not seen such with earlier GAMS versions.

Ok, I tested a bit with GAMS v34.2, and the cause of the problem is that they have changed the output from the GDXDUMP utility.  And that happens to be crucial for filtering out any domain violations.

This means that under GAMS v34.2 TIMES will not work with models having domain violations. At least until I can figure out how to fix this issue.

Therefore, if you can use an older GAMS system, I would suggest to use that instead, or make sure that you have no domain violations in your model (albeit often harmless, they may be considered modeling errors anyway).

With the latest TIMES v4.5.2 the above-mentioned problem with GAMS v34.2 (under domain violations) should be fixed.

Super many thanks!!

(As you described, with the previous version it works as long as I didn't have any domain violations)

Will I have the latest TIMES v4.5.2 per default next time I update VEDA? Or do I need to download this separate?

Have a look at Tools → Update TIMES Code.  I tried that and it worked: It created a new source code folder GAMS_SrcTIMES.v4.5.2.
   

[Anna (AKR)]

That worked, and the model is now running with TIMES v4.5.2.

I haven't tested with domain violations, yet, (but I am sure I will do so within the coming week, because we are merging two models...)

Thank you very much!
