lost the 3D Geometry tab

In one of my models I have lost the 3-D Geometry tab - any idea of how to
get it back?

TIA.

If you mean the 3D view is blank (typical on opening a large previous
project in my experience), that's something easily corrected by running
a simulation in my experience... if there's a faster way I'd like to
hear it though!

If you mean you've literally lost the tab on the top - that's weird! I
don't have any answers for you, but it might help to post a screenshot.

The tab is really gone - see attached. It seems to be when I set
SHADING-SURFACE = YES. I haven't tested this many times yet though as the
model takes a long time to open.

Susan,

my guess is that this is a memory/refresh issue that eQuest & your computer
are fighting about. If you have many other programs open while you are
trying to run a really LARGE eQuest file you will run into issues with the
3-D graphic viewer and memory problems.

As far as "testing"--we are engineers & scientist and all good models and
all good simulators run "tests" or "experiments" to better understand how
the program is behaving. Remember two things:

1) if you are not "testing" your models, you are not doing quality work to
make yourself a good simulator--(I hate it too sometimes, but I have to
force myself to be the scientist that I am and that I was trained to be. We
have to "suck it up" and take the extra time to do the extra work.

2) just because you see a problem with eQuest itself doesn't always mean
that there is a problem with your simulation (DOE-2.2) results...remember
that eQuest is a user interface and effectively eQuest is only the
translator between you (the user) and DOE-2 the simulation engine.
Sometimes if you can get by with out having to see the 3-D model images you
can still run your simulations without the visual reference. If you don't
need to look at your 3-D model view you should still be okay to continue
with your inputs and go foward with your simulation.

For more assistance post your .pd2 & .inp file for others to look at,
however where you had mentioned your file takes soooo long to open this is
discouraging to those of us that are trying to meet our own project
deadlines. One other thought for the future is to work with an experienced
modeler or attend a training class where you can learn how to simplify your
models and inputs for the sake of a more efficient model file without losing
design details that will affect the energy consumption.

My immediate advice would be: close every other program you are running
simultaneously, and it might even be beneficial to just restart your
computer to clear it's memory, and then run some experiments to know what
this visual error is or is not affecting in your model, try and figure out
how you can re-zone your model so that it simplifies the run times on your
model.

As far as testing - I absolutely do spend a great deal of time testing my
models. My point was that I haven't had a chance today to determine if the
issue was only occurring as a direct result of selecting the self shading.

I don't need the 3-D view other than to visually inspect the input that was
done by others.

I will try closing everything else to see if it helps. I have had
significant issues with the size of this model.

Thanks for the response.

I'd put $20 on it being a hardware issue with your graphics card.
eQuest is pretty taxing on your graphics card, and I've had models that
show a 3D view tab on some computers but don't show it on similarly
equipped computers with lesser graphics cards.

Try it on another computer and see if you have any luck!
