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.

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
.
23.0	2500	0.3
23.1	0	0
25	0	0

0.0	0.0	0.000
1.0	0.0	0.000
2.0	0.0	0.000
