Does OpenFAST allow negative fine pitch angle? #2411

Closed GBA217 closed 1 month ago

GBA217 commented 1 month ago

Hi, I'm trying to run a Ramp simulation with negative fine pitch angle (-0.017453300000 ! PC_FinePit) but, the pitch angle doesn't seem to go below zero. I have set minimum physical pitch (PC_MinPit) allowed to -0.34906000000 rad but it doesnt seem to help. Does OpenFAST allow negative fine pitch angle? image

Hi, this is probably more of a ROSCO issue. You may also need to set PS_Mode to 0.

Seting PS_Mode to 0 works. Thanks
