I am simulating flow past bluff body. I have created a flow domain(1) and a bluff body. To capture vortex shed from body, I need finer mesh near bluff body and so i created another small domain (2). I did boolean to subtract the bluff body from two domains created. Now the second domain(2) is considered by fluent as 'wall-solid'. I am able to run the simulation and get results for sphere but I am not sure what I am doing is correct or not.

Yes, your approach is correct. Please refer to the following course, where similar conditions are used, and in particular, check the mesh lesson.

Thanks. I will check the video.

Domain 2 should be bounded by interior: I assume you used Share Topology?

I did not explicitly give a shared topology option. I will go back and see geometry and mesh again. Thanks for your response.

Just to clarify. If domain 2 is a body of influence it doesn't need to be linked to the main geometry, if it's been subtracted/split then it does with share topology. The videos/course should cover this.

Really helpful- I was trying shared topology yesterday but it did not show any shared region. I am using domain 2 as body of influence for finer mesh. Thanks for your reply.
