Dear OpenFAST users,  
Does anyone have a DTU10MW Beamdyn\_Blades.dat file? The file I’m using may be wrong, I hope to get your help.

Best regards

Dear @ShiXuan.Li,

> Hi, I need clarifications about the relationships between coordinates system of DTU 10MW RWT and FAST’s coordinate system. In particular I’m confused for what concern the pitch rotation: in order to perform correct computation with FAST I need to add the structual twist of the blade (obtained from DTU 10MW RWT structural properties documentation based on HAWC2 computation) in the blade input file required by ElastoDyn with opposite sign respect to the 10MW RWT documentation. Furthermore, I tr…

> Dear all, The DTU10MW model hosted by the DTU ([url][Files · master · DTU 10MW RWT / dtu-10mw-rwt · GitLab](https://rwt.windenergy.dtu.dk/dtu10mw/dtu-10mw-rwt/-/tree/master/aeroelastic_models/fast%5B/url%5D)) has only the aerodyn14, but the linearization of the FAST or openFAST supports only the aerodyn15. I tried to replace the areodyn14 model in DTU 10 MW with the aerodyn15 files in IEA-10.0-198-RWT ([url][https://github.com/IEAWindTask37/IEA-10.0-198-RWT[/url]](https://github.com/IEAWindTask37/IEA-10.0-198-RWT%5B/url%5D)). I do not know much about the IEA-10.0-198-RWT model, but it seems the power rated power is not 10 MW anymore after the replacement. …
