      WindSim 8.0.0 | Known Issues

      Wind Fields Module:When exporting wrg or rsf files with non-integer numbers higher than 100 the wrong value after the decimal is given.
      Workaround: Open the file and make a [search and replace] with the correct value .
      Versions Affected: WindSim 8.0.0


      Terrain Module:When using the forest model the default C2 parameter is given for the old forest model.
      Workaround: Use a value between 0.01 and 10 to get reasonable results.
      Versions Affected: WindSim 8.0.0


      Terrain Module:When using a refinement file the simulation will break if the overall area is larger than the area given in the refinement file.
      Workaround: Set the x-range and the y-range to the same value as in the refinement file.
      Versions Affected: WindSim 8.0.0

      WindSim 7.0:Missing some Chinese translation.
      Workaround: Download this file and follow this steps:
      1)Unzip the gui.zh-CHS.zip
      2)Copy the Unziped file gui.zh-CHS.resources to the root of WindSim 7.0 (C:\Program Files...\WindSim\WindSim 7.0.0\) and replace the existance one
      Versions Affected: WindSim 7.0.0


      Losses&Uncertainties:The sensitivity factor is not calculated in the right way.
      Workaround: Use the WindSim_core.exe from 6.2 to run the energy module and afterwards run the losses&uncertainties. Go to C:\Program Files (x86)\WindSim\WindSim 7.0.0\bin rename WindSim_core.exe to WindSim_core_7.exe and place the WindSim_core.exe from C:\Program Files (x86)\WindSim\WindSim 6.2.0\bin there. Run energy and losses and uncertainties and then rename WindSim_core.exe to WindSim_core_6.exe and WindSim_core_7.exe to WindSim_core.exe. If you don’t have the WindSim_core.exe for WindSim 6.2 just contact support@windsim.com.

      Tools/Create power curve:Wrong interpolation of the power curve if the cut out wind speed is lower than 25 m/s.
      If no values are given for the wind speeds higher than the cut out wind speed the values will be set to the cut out wind speed until 25 m/s.

      Workaround: Fill up the bins until 25 m/s with 0.0 m/s e.g.

      Power curve with cut out 23 m/s:

      Bin (m/s) Power(kW) Thrust Coef. (-)
      3.0 50 0.2
      4.0 108 0.4
      .
