[Equest-users] General Advice

eQuesters,
 
    I have solved my problem, described below (from previous e-mails).  My
solution leads me to send the following advice to everyone:
 
    Be aware that adding comments (i.e. text preceded by a dollar sign) in a
.inp file, even at the end of an already functional line of code, can cause
mysterious problems in eQuest's interpretation of other (seemingly
unrelated) lines of code.

eQuesters & Brett,
 
    Thanks for your help, Brett.  The BDL file shows the following.  It also
showed the same error with or without quotes around the U-name in line 3017
and with or without the $ in line 3010.  Evidently, eQuest is just not
recognizing the parent system that I defined line lines 2994 - 3016.
    Does anyone know why this would be - especially when, as explained in
the original e-mail (below), I based this code on that generated by eQuest?

Lars,

 

My suggestion would be to open the bdl file and search for "error".  This
will indicated direct you to where error occurred.  Too many errors and
eQuest gives up.

 

If you are manually editing the inp file, make sure you have two periods
".." at the end of you commands as required.

eQuesters,

 

    I included the following text in my .inp file, copied-and-pasted from an
.inp file that eQuest generated.  My intention is to edit it to reflect the
conditions of the present project, which I really really don't want to have
to re-create in the wizard, since I've already composed about 3,000 lines of
.inp code for complex geometry, schedules, etc.  As of yet, the only thing
that I've edited are the U-names referring to the fan schedule, the heat
schedule, the cool schedule, and the space - so that they match the present
project.  Scrolling down in this e-mail, you'll see the lovely error
messages that appear when I load the .inp file into eQuest.  Can anyone tell
me what is wrong and how to fix it?  (Yes, I clicked on the errors, but
eQuest tells me nothing helpful.)

    By the way, my concern here is only with HVAC errors and not with the
electric meter error, which simply results from me having commented-out the
electric meter code in the .inp file.

    Thanks if you have advice...
