Editing DOE-2.1e/eQuest Weather Files

To whom it may concern,
I am trying to edit a DOE-2.1e/eQuest weather file.? The instructions pointed the use of an Excel file called "Custom_eQuest_Weather_data.xls" and another file called "PSYCH.xla".? In fact, there is a previous post with the same problem:

I realized that there are no "Custom_eQuest_Weather_data.xls" and "PSYCH.xla" files in the DOE22WeatherUtilities.zip from DOE2.com.? I followed the instructions until I hit on a wall once I tried to pack a new weather file through the PKAFT.bat.? Once I ran the PKAFT.bat, I got an error, and the new BIN file appeared empty.? My first idea is that the lack of the "Custom_eQuest_Weather_data.xls" file is bringing me this problem.? The columns in the second FT file have lots of space between them, and do not look like the original FT file.? Can I get a copy of this file from DOE2.com or any other source? Any comments will be highly appreciated!

Jose,

You've probably run into a 3rd party custom tool which isn't part of the
standard DOE2 package. It shouldn't be the reason for your errors. These
tools are fairly common and would probably be used in the following
scenario:

1. You have actual hourly drybulb, pressure, and wetbulb data that you
would like to put into a custom DOE2 weather file.
2. DOE2 weather files have records for drybulb, pressure, wetbulb, humidity
ratio, air density, and enthalpy among other things. Technically, you only
need 3 of these to set the state of the air for an hour, but the program
doesn't do this calculation for you, so you need to make sure that they
correspond to the same state before you pack the weather file.
3. You use some pscychrometric tool to take your hourly drybulb, pressure,
and wetbulb data and calculate the corresponding humidity ratio, density,
and specific enthalpy.
4. Run FMTWTH program to pack the weather file to binary form.

I would recommend taking a look at something like Elements from BigLadder
Software which does most of this for you in a spreadsheet style view. Or
look into purchasing custom data.

Also, eQuest runs DOE2.2 and DOE2.3, but the weather format hasn't changed
from 2.1.

Dear Mr. Powers,
Thank you for your response!? How can I get a copy of the FMTWTH program?
Kind regards,

The weather processor files and documentation can be downloaded from this site:

Please note that the utility program names Chris mentioned are those in DOE-2.1E and
before. The program names on the doe2.com web site have been changed, although the
programs are the same:

wthfmt2.f == BIN2TXT (goes from *.bin to *.fmt)
fmtwth2.f == TXT2BIN (goes from *.fmt to *.bin)

Both of these are compiled Fortran programs, so you would have to run them in a Command
Line window (horrors!), in which the programs expect the *.bin file to be called
WEATHER.BIN and the *.fmt file to be called WEATHER.FMT. In addition, ftmwth2 needs a
single line INPUT.TMP file telling the program whether the *.bin file has solar data or
not (99.9% of the instances now always "yes" but in the early days DOE-2 would calculate
the solar using very old routines in case the weather file didn't have it). To automate
the renaming of files and generating the INPUT.TMP, the doe2.com web site provides two
MS-DOS batch scripts MKAFT.BAT and PKAFT.BAT. These are essentially the same as the two
MS-DOS batch scripts I use, except for the changed names of the two programs:

dowthfmt.bat:
copy ..\Packed\%1.bin WEATHER.BIN
wthfmt2
move WEATHER.FMT ..\unpacked\%1.fmt
erase WEATHER.BIN

to run, just type "dowthfmt [bin file name without the *.bin extension]"
(this assumes that the %1.bin file is in the ..\Packed\ directory

dofmtwth.bat:
if %2 == S echo 2 5 > FMTWTH.INP
if %2 == NS echo 2 2 > FMTWTH.INP
copy ..\Unpacked\%1.fmt WEATHER.FMT
fmtwth2
move WEATHER.BIN ..\Packed\%1.BIN
erase WEATHER.*

to run, type "dofmtwth [weather file name without the *.fmt extension] S"
(S indicates the weather file contains solar, this assumes that the %1.fmt file is in the
..\Unpacked\ directory)

If you continue to have problems with getting things to work, you can also download my
original copies of wthfmt2 and fmtwth2 at
