How can I solve the problem like overlapping grid in CFX

Dear everyone,
Is there anyone who know about the overlapping grid in CFX? For example, I want to simulate the flow around the circular cylinder. And I have generated the grid_1 of the cylinder, as shown in fig1. Now, I need to interpolate the flow quantities into an independent rectangular block of grid_2 in every time step so that I can just get the data in grid_2 to save my disk space. From the fig2, It can be noted that the the grid_2 is just an overlapping grid and have no connections with the grid_1.
So would you please tell me how can I set the .def in CFX_Pre to solve the problem? Many thanks!
