corrupt .sim file

Hi All,
Has anybody restored the .sim file before?
My eQuest model opens with no errors, runs with no errors, displays
reports within the eQuest interface and also has no errors in the bdl
file. Although, the .sim file alone would not open at all.
Occasionally I get a prompt that says that the .sim file is corrupt.
I have tried to start a new pd2 and import the .inp alone to create a
new file, but that still did not solve the .sim file issue.
One thing I noticed is that typically most .sim files range in the 15
- 30 MB file size. The .sim file that does not work reads a whopping
300 mb. I guess that should have raised a red flag, but I did not
catch it in time.
Any suggestions anybody on how I can keep all my work and restore the
corrupt .sim file? The model now is useless to me without the details
offered in the sim file.
Thanks much

Here's some more info on the error listed below -

We managed to open the .sim file in 'Notetab' instead of the
DoeSimviewer. Most of the zones have a warning

**WARNING**********************************************************************
Zone: EL5 SE Perim Zn (G.SE22) could not successfully
allocate all equipment energy to the 5-minute bins
because of an equipment overload. The peak load
used in ECONOMICS will not include the fraction due
to the overload, but the PLANT reports will.
Mon/Day/Hour: 1 1 2 Energy: 1.9 Unallocated: 0.248

I do have 400 + zones? Is that maybe a no. of zones overload?

Sangeetha -

I think this error could have a number of sources.

The last time we encountered it, we had a large number of that type of error, and the values in various reports (BEPS, BEPU, etc) were over-written (I think with $$$$$$ or XXXXXX, I can't remember - looked like an overflow error to me).

We switched out the part-load curves associated with the HVAC equipment we were using, and the error resolved.

I'm not sure I can explain the rationale for why this happened - both curves were default curves - but it may give you an idea to check into.

All the best,
