GenCumulativeSky - problem of reading .epw file

Dear Christoph,

Thanks for your quick reply. I sent it to this list because people here are
probably more interested in using the .exe file directly. I'm glad that it
catches your attention here.

Back to the question. I have typed in the following to the DOS command line,
and have put the weather file "SGP_Singapore.486980_IWEC.epw" in the "D:\test"
folder.

D:\test> GenCumulativeSky +s2 -a 1.36667 -o 103.96667 -m 120 -E -time 0 24 -date
1 1 12 31 SGP_Singapore.486980_IWEC.epw > sgsky.cal

It resulted in the following messages:

Error opening: SGP_Singapore.486980_IWEC.epw
GenCumulativeSky: Error reading climate file SGP_Singapore.486980_IWEC.epw

Could you take a look and see whether I did anything wrong? Thanks a lot!

Regards,
Kam

Dear Kam,

I just played around with the gencumulativesky.exe that ships with DIVA and the input for the *.epw file location is a little weird. Here is what I found:

A full windows directory path does not work specified with either backslashes or forward slashes. i.e. C:\boston.epw and C:/boston.epw both cause your error.

Putting the simple filename as in the example you show above also causes such an error.

However, there is light at the end of the tunnel! For me, putting a path name such as ./boston.epw works.
example: GenCumulativeSky +s1 -a 1 -o -104 -m -105 -r -E -time 0 24 -date 1 1 12 31 ./boston.epw > example.cal

This markup is exactly what DIVA uses in its generated batch files; however I was not aware that conventional file location inputs would break the program. Just make sure that your current working directory and the location of the epw file are the same.

Let us know if you continue to have problems.

Best of luck,
Alstan
