CFD External flow in wind turbine

CFD External flow in wind turbine

(OP)
Hello,

I have modelled a wind turbine and like to rotate it through wind force using CFD. In the beginning I made a model in CFD with walls, inlet outlet and other things and also made fluid surface interaction with wind blade in elastic model. The software am using is Abaqus. The thing it rotated even though I did not apply angular velocity in wind turbine. It rotated with the wind force to some angle around 15 degrees and stopped and it showed executable file error. So I later came to know that I have to rotate the mesh in CFD too but in boundary condition option there is only U1,U2,U3 there is no rotation R1,R2,R3 option. so how can I apply rotation and also how can I match it with velocity of wind blade that rotates due to inlet velocity?

Please help me with this
