I have tried a lot of different thinks to create a mesh where FLUENT can recognize the different cell zones, but so far I have not been able to achieve that, so far It recognize everything except the 3 different cell zones that I am trying to create, the last thing that I did was to use the Slice option at the DM to create 3 different areas (or parts), but to do that I had to create 2 lines from sketches, I think that there is my mistake, but I need someone to correct me, this is a simple 2D problem, please someone help me. Any tutorial/guide/material will be appreciated but I have not been able to find anything at the DM/Meshing level all the information that I was able to found was at the Fluent level, and my problem is before that.

Thanks
