File .lib and .gwc

[trantduc]

Hello WAsP Team,

I am encountering an issue with data usage. Previously, I would import a .tab file, map vectors in WAsP, perform calculations, and obtain a .lib file. In Winpro, I utilized this .lib file as wind statistics in Site data. However, in the latest version of WAsP, the .lib file has been replaced by a .gwc file. Unfortunately, the wind statistics in Site Data currently only accepts .lib files.

Could you please assist me in using the .gwc file appropriately so that I can use it for park calculations?

Thank you for your support.

Best regards,
Trantduc

We updated the wind climate models and the new model parameters are not supported by the old LIB file format.

If you need a LIB file for a special purpose, you must recalculate the GWC without the new model options before you can export it to file. Follow this procedure:

1. Right-click the GWC and select Show GWC from the popup menu.
2. Open the Stability panel and select the old EWA profile model from the drop-down menu.
3. Open the Geostrophic shear panel and hit the Turn off button
4. Close the GWC and recalculate it
5. Right-click the GWC and select the Export GWC to legacy format option from the popup menu.         

For WAsP calculations, we definitely recommend GWC calculations by the updated model and export to the new GWC file format.
Maybe you can seek advice from the WindPro developers about the best workflow for their program.

Best regards,
Morten
