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

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.


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:

| Editing eQuest Weather Files | Energy-Models.comHi, I'm working on a calibrated energy model using eQuest. The client has specified that they would like weather data for this model to be taken recently from a local weather station.  |

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!
