3 bodies in 1 part

Atit

I create the domain as 1 part which contains 3 bodies. In CFX-Pre, I assign the volumetric heat source to B2.P3 (the 2nd body in the domain). When Solver run, the residues fluctuate and converge very slow. When I visualize the result in CFX-Post, I found that the source is at B3.P3 (the 3rd body in the domain). I check from the output file of Solver, it says that the source is at B2.P3. Then I run that definition file again after 10 loops, I stop Solver and see the result file in CFX-Post, the source is at B2.P3, then I run the definition file by Solver again. At about the 100th loop of the third adaptive mesh process, the residues fluctuate, then I stop Solver, and see the result in CFX-Pre. I found that the source is at B3.P3. This is very weird! Do anybody have an idea what wrong with my model? Thank you very much.
