Divergence detected in AMG Solver
 
Hello guys,
I am in need of assistance, I am working on a paddlewheel submerged in a river (low-head power generation) in ANSYS fluent. The paddle-wheels are in 3 sets. The output profile of the previous is read into the next in order to achieve a continuity of flow. But on running the simulation for the second paddle-wheel whose input is the output of the first(previous), I am getting a "divergence detected in AMG solver" what could be the case. Secondly, when dealing with reference frames, where you have a rotating zone and a stationary zone, how does one define the moving wall and stationary walls boundary conditions. Your reply is much appreciated and awaited.
Thanks
