I want to simulate a simple natural convection heat transfer of a sphere in a box. Firstly, I created a blockMesh geometry and then I merged it with gmsh sphere. Sphere is 400K and y1,y2 is 290K, other BCs zeroGradient. When i'm run it there is no heat transfer between sphere and air. If something wrong with merging should i continue with chtMultiRegion? I'm open to any suggestions. I added the case in attachment.
