Hi,

i am doing a flow simulation analisys with a  rotating turbine ,i need the fluid-structure interaction (FSI) between the water and turbine blades to provide the torque to turn the turbine and make the cp ,T.S.R curve .but i can´t mesh correctly the airfoil blades.

what kinds of  mesh parameters are useful for this? I put variable values on local meshing but the result is not ok.

Thanks.
