Re: Help running FAST v8 for the first time

Dear Jason

Thanks for your help!
In the topic: viewtopic.php?f=4&t=2139&p=11929 , Yichau said you have a privious report "Simulation for wind turbine generators-with FAST and MATLAB-Simulink Modules".
Could you share it with me ?

Best regards!

Re: 15MW MaineSemi-sub floater simulation shows tower strike

Dear Jason I ran the 15MW model and got the output file.In the output data I want to find what I need,but all abbreviations. I can recognize some of the names because they are the same as those in V8,and I don’t recognize someelse. Do you know the specific meaning of these abbreviations? Best Regards!
