How to set different zone in OpenFOAM?

feiqunali · October 16, 2011, 03:57

I want to simulate flow of flapping airfoil using dynamic mesh. The computational grid is like this: surrounding the airfoil is structured grid and all the points moving in the same velocity as the airfoil;Out of the Structured grid is unstructured grid and outer boundary of the unstructured grid is static. I have known how to generate such grid but I do not know how to set the case in OpenFOAM(i.e. how to divide the mesh into different zones and set different mesh motion solvers respectively). So does anybody know and tell me? Thanks very much!
