Equest 3.6 simulation bug

Hi,
I am having a problem w/the equest program. When I run a simulation, it
gets to 18% complete, and the freezes up. It displays 'ready' in the
bottom right corner, but no calculations are being performed. If I
click anywhere in the program window, it lists 'not responding'. I've
already uninstalled and reinstalled the program with similar results.
Is there any way to solve this problem? I am currently at a dead end
and am not sure of any way to perform a simulation at this point. Any
help would be greatly appreciated. thx.

Are you running in Windows Vista? If you are, eQUEST must have
administrator privileges to write files where it needs to. If you are
getting any kind of output file, the end of the .sim file or the .bdl file
should give you an indication of what is going wrong.

I had a similar problem some time ago. The issue was resolved with
minimum data loss by opening a new, blank file and then importing the
.inp file from the original. I lost my Wizard data but was beyond that
in the project.

Good luck!

I have been struggling with an issue on a large campus energy model. I am
trying to model the chilled water system, which is a campus system simply as
metered energy. I have basically indicated a chilled water meter of the
chilled water loop. My problem is that when I simply replace a chiller with
the chilled water meter and re-run the model my space cooling energy
consumption goes up dramatically (over 2 times). I have been working on
this for a long time, and cannot seem to figure out what is causing the
chilled water meter to (virtually) create additional chilled water energy
consumption on the chilled water loop.

Does anyone have familiarity with this issue?

Make sure you are looking at comparable reports - the chilled water
demand should be the same in the two cases, but the purchased energy
will be quite different as in one case you are purchasing the chilled
water btu's directly, the other you are purchasing electricity to
produce CHW at some COP, so the two quantities will be different by that
ratio.

Mike,
I'm running XP SP2, so that's not an issue. I checked the bdl file and
sim file, no obvious issues.

Brian,
I tried the .inp import technique.....unfortunately, I have the same
freezing issue. Any other possibilities?

I had a similar problem once and it turned out to be the result of a blip in
the weather file. I can't remember which file it was (one of the standardly
available TMY/TMY2), but perhaps try running your model with a different
one. Or, run the model with 'pause on errors', and that should give you a
better idea of where the problem is coming from.

Cheers,
