Thank you very much for your reply. I have a preliminary understanding of PyWake. In the official PyWake document, PyWake WAsPGridSiteproposes: providing a WAsP terrain interface to consider the impact of terrain on wind farm power generation. Has this idea been realized or is it just a way for the DTU team to improve PyWake later? If it has been realized, is the combination of PyWake and WAsP realized through WAsP software generating elevation contour vector maps?
