Walif, I think it is the "Line X>" text that is causing the problem. You should have a file with only numbers in it. If you are using Trnsys17, there is an example file in: ..\Trnsys17\Examples\DataFiles\Type51-CoolingTower.dat Alternatively, you can look in the Type51 section of the 04-MathematicalReference manual (for both Trnsys16 and Trnsys17) to see an example data file.
