Hello All,

When modelling a turbine I would like to have periodicity in the mesh. For example if I have six blades in a turbine I would like to mesh one sixths of a cylinder-shaped region and then copy the mesh to the remaining space (like copying a piece of pizza six times to create the pizza). I am not sure whether ANSYS Meshing supports this, and if so, then how it is called and how to use it.

Additionally when modelling, is it possible to run cfd simulation only on the one piece of the pizza and then copy the results to the remaining pieces. This is like symmetry but not on a face, rather on three dimensional bodies. As I am using steady state simulation with frozen rotor, can this be useful when the turbine is moving forward without an angle...?

Regards,
Svetlana
