Rogier Thank you very much for your kind reply. Does that mean, all the old GWC files that we have will not work unless we create our new GWC file? but I also downloaded one GWC from Global wind atlas website for some location and the same problem also appeared. The Support portal is not working properly and it freezes after a short time. Is there any email i can send my concerns in? Regards, Salwam

Dear WAsp Team Its seems to be new features (Not sure if its new features or its my mistake) with WAsp 12 regarding using of Generalized wind climate files. When i try to do new project and insert GWC from file, WAsp shows me Red triangle (calculation constraint) There is no observed wind climate associated with wind atlas. I used some old wind atlas files and even some file downloaded from the global wind atlas website but its the same. I can remember that i am following the same procedure for slightly more than a year before and it was ok but not now. I will keep reading if there are some new changes but if you have any helpful input pls. do share it with me. Thanks in advance Salwan, VIA University college/Horsens-DK
