Can some one suggest me a method or a possible way to work on problem having non matching grids at one place and also need to have a rotatory model at an other end.

Searched and found that ggi handles both the problems. I cannot find the actual details of ggi and so can someone suggest me how to handle the two problems i have stated above.

Best regards,

Can someone tell me if i can use different rotating velocities to two different regions at the same time in ggi.

This has nothing to do with the GGI interface.

The GGI interface is just a "transfer function" for interpolating flow values across non-matching patches.

What you need is a solver that will support different rotating velocities in different regions. For this, you need a solver that will support Multiple Reference Frames.

Thanks Martin, But can you suggest me some solvers for this case ? And the other question is, in the DynamicMeshDict file we define the velocity(RPM) in ggi case, but if i want two have two different velocities for different regions?
