I know this question has been asked before, I am a new user and just following the tutorials at the moment which are in the help content. I have been given Raster files .*TFW & .*TIFF format and .*WRG files for a site, now I have opened them in OpenWind and I am able to run wind farm optimisation and other calculation, but I really want to learn WAsP11, is there a way to convert .WRG file into a format which WasP11 can accept. Where can I find more tutorials, videos preferably. many thanks CranfieldUni student
