MSG[0]: SVAL LOOKUP ERROR trnsys.user_trdsrc

I'm getting the below error list in SAM when i try to run the simulations on my MAC OS X 10.8.4. I'm referring to a .csv weather file saved in a separate folder after adding the said folder in SAM. Even if i select a file from the SAM library and save it in this folder and try to refer, the simulation renders same errors.

Hello,

A problem with the weather file may be causing the problem. Are you using one of the standard TMY2 or TMY3 files from the NREL NSRDB database, or a file from a different source?

If you are using a file from another source, please attach it to your original message, and I will see if I can see what might be causing the problem.

Best regards,
Paul.

Hi Paul!

I have attached the weather file. While it is running in Windows, it is showing the above error in IOS. Yes i'm using the standard file from NREL NSRDB database.

Best Regards

JP

Dear JP,
The weather file you attached does not appear to be in the correct TMY3 format. For example, the direct normal irradiance values vary from -10,000 to over 100,000. For hourly irradiance data in W/m2, I would expect the values to range from zero to around 1,000.
Best regards,

Paul.
