Hi

I need to simulate the 2D savonius wind turbine in fluent.

For this I created a mesh in Gambit. In Gambit there is one domain that contains the wind turbine domain, i.e a large rectangle containig a circle enclosing thw wind turbine. An interface is added so as to connect the mesh in Fluent.

In Fluent, I use Define->Grid Interfaces to set up the interface. As there are two domains: the one enclosing the the turbine is the rotating fluid which I set it to Moving Mesh and give it a certain rpm. The blade walls are aslo set to rotational motion. Standard k-e model is used and the inlet is velocity inlet and the outlet is pressure outlet.

Using the above process I try to iterate but i never achieve convergence of 1e-3.

Please tell me what I am doing wrong.

Thanks in advance
