Error running wind data file was created by danny_13

Good day

I am trying to run a wind data file. The simulation starts running, but half way through it gives this error:

compute fail(windpower): invalid stof argument
Simulation windpower failed :compute fail(windpower): invalid stof argument

Any assistance would be greatly appreciated.

Kind regards
Daniel

Hi Daniel,

This error is caused by a missing temperature value in Line 5287 of the file you sent me by email.

I used a text editor to delete the trailing comma(s) at the end of each data rows, and then tried running a Wind simulation in SAM and got a more helpful error message "error reading wind resource file for interpolation at time step 5284: line contains 3 columns, should contain 4." (Because of the two header rows, Time Step 5284 is equivalent to Line 5287, where time steps start at zero and lines start at one.)
