is there a way back from this error?

Hi,
I get the following error multiple times when trying to finish a retirement center with multiple bld's, shells and units....equest runs a long time.
Is there a way to fix it or I go back to my previous files to retrieve left over info? The 3D is not generating looks like adding last bld's did it...
Thanks,
Nikola

Nikola,
That error should not affect the model. It loaded fine on my computer
despite the error window, though it did take a long time.
After you load the model, did you try resetting the camera? Something as
simple as restarting the computer or changing the file name has also
helped me in the past on larger models.
Best of luck.

Do you have any sloped roofs? Try getting rid of them.

I'm trying to incorporate supply air static pressure reset in a VAV system - where the static pressure resets lower as cooling demands decrease. I have a two part question:

1. How do I capture this in eQUEST. I've been through the archives and it seems that the way to do this is by modifying the fan curve - is this the only way? There' one post from 2002 (http://lists.onebuilding.org/pipermail/bldg-sim-onebuilding.org/2002-October/000777.html) that references this being added as a feature - has that happened?

2. If the building is looking at adding supply air temperature reset - will static pressure reset really do much? Assuming the cooling load drops and the supply air temperature gets reset higher - you will be moving close to the same amount of air - so I would think that the pressure reset wouldn't do much - right?

Thanks for your help (in advance)

Nikola,

Don't worry about it - I've had that message come up before. It didn't affect anything - it was a pretty large model with a number of custom polygons - is that what you have too?

Hi Sami,

Yes, large model with lots of custom polygons......the message is gone, project loads but I still can't view the 3-D, I see the shells only in 2-D.
*I got several responses from various users on the camera reset, latest being from Josh Greenfield that I'm pasting it below, since interesting thing-Josh can see the 3-D pix from the zip file I sent, but I can't.....go figure?!?

Anything else I can try on my end?
It's weird that Umesh and Josh can see the 3-D from model I sent and I'm not able to.

Best,
N

This isn't too strange - that error is related to processing of the 3D
image, and that capability is tied directly to your video card and
general processor.

Maybe try it on a higher powered computer?

FWIW, I've observed the same error on smallish models with detailed geometry edits. I don't think the error is size-dependant (though size may be a contributing factor to the difficulties in getting the 3D views to play nicely). I know the same error comes up from wizard-borne pitched roof inputs on occasion.

I have the same sense as others of this being generally erroneous if no other errors or warnings occur on loading/simulation (I'd certainly double-check for my own model). My theory is the error is specifically getting at a difficulty in rendering the 3D view - which is to say there is zero effect in regards to the actual simulation/results. In other cases, I've observed models with this "triangulation" error partially render the 3D view, with some surfaces not being drawn at all, but still existing in the component tree with all appropriate ties.

Oh and here's a related post from Mr. Criswell some time ago for further reassurance: http://www.gard.com/ml/bldg-sim-archive/msg04131.html

Nikola,
I know this does not aid the issue at hand directly, but is there a
reason for you to have so many individual windows (and their respective
overhangs) vs
just single strips? Doing this would considerably speed up your model.

Nikola,

You have a lot of "Custom zone xx" polygons in your pd2 file, that I have
found have given me this message in the past. Try deleting the one that
starts at line 1172 (I'm not sure if the line numbers correlate with the
line number in the VTK window.)

Thanks everyone for your input, I really appreciate your feedback on the matter!
Problem is solved (for now at least).

Best,
Nikola

Ps. As a token of appreciation, here is warm regard from sunny San Francisco if you haven't seen it so far.
