about FSI and Joins

i am trying to simulate a 2 way FSI on cfx and ansys design space , the solid part is a propeler that has 3 wings and the fluid is air at the speed of 2 m/sec,

the problem that i have is that in the ansys i put as joint a body to ground joint to the axis of the propeler. when i run the fsi simulation the ansys design space get me an error that the joint is not working. so i though to do only the stuctural to see why it is not working, the problem is on the joint of the propeller shaft to the ground, i first put a joint to ground but it was not working,,,, then i put a cyllidricaly support... the same error

can anyone tell me what i shall put to the shaft so it would rotate but not move ????

best regards kanton eddy
