WindSim 5.1.0 | Known Issues
Tools/Create power curve:Wrong interpolation of the power curve if the first and last value is not 0.
Workaround: Add a bin close to the first/last bin which has the value 0 e.g.
Power curve:
| Bin (m/s) | Power(kW) | Thrust Coef. (-) |
| 2.9 | 0 | 0 |
| 3.0 | 50 | 0.2 |
| 4.0 | 108 | 0.4 |

| 25 | 2500 | 0.8 |
| 25.1 | 0 | 0 |
Versions Affected: WindSim 5.1.0
Power Curve:In case you create your pws file on your own the bins have to be regular 1m/s bins and the file has to start with bin 0 e.g.
Power curve:
| Bin (m/s) | Power(kW) | Thrust Coef. (-) |
| 0.0 | 0.0 | 0.000 |
| 1.0 | 0.0 | 0.000 |
| 2.0 | 0.0 | 0.000 |
| 3.0 | 0.0 | 0.000 |
Versions Affected: All WindSim versions
Terrain Module: Forest creation does not work correctly
Workaround: Install Patch 1 of WindSim 5.1.0 version, see Updates.
Versions Affected: WindSim 5.1.0
Terrain Module: WindSim smoothing with refinement area does not work correctly
Workaround: Install Patch 1 of WindSim 5.1.0 version, see Updates.
Versions Affected: WindSim 5.1.0
Wind Fields Module: The temperature effects influence the convergence ability of the coupled solver.
Workaround: Use the segregated solver when using temperature.
Versions Affected: WindSim 5.1.0
Wind Fields Module: When running in batch mode sometimes the last sector is not displayed in the tables after the run.
Workaround: Close and reopen WindSim.
Versions Affected: WindSim 5.1.0
Wind Fields Module: The k-omega model is not working with temperature.
Workaround: None.
Versions Affected: WindSim 5.1.0
Wind Resource Module: Reporting fails if the first climatology is made invisible.
Workaround: Take a layout copy and delete the first climatology if you do not intend to use it.
Versions Affected: WindSim 5.1.0
Energy Module: Negative speed values in power history if wake effect are too high.
Workaround: Install Patch 1 of WindSim 5.1.0 version, see Updates.
Versions Affected: WindSim 5.1.0
Terrain conversion: The terrain conversion fails in the evaluation version and in the big_model version.
Workaround: Use the terrain conversion from the normal version.
