Proper Meshing

      Hey there, I created a geometry for a double pipe heat exchanger and meshed it. so far so good. But the fluid in the inner pipe is seen as a hollow cylinder in the meshing tool although it is a full body in the DesignModeler. I created the pipes via extrusion and the fluids via filling the pipes... Now I need the meshing tool to understand that the fluid is not a hollow cylinder, so I can mark the inlet and that the simulation will give me some usefull results.

      Would be really happy about any help!

      Thank you guys :)

      Are you able to see that solid in structure tree? nSelect that body. Go to details and change transparency. nPlease also have a look at share topology. nPlease check following videosnnDM Share

      Thank you Keyur for the help, I tried to change the shared topology, but it didn't help.... I noticed that when I take the body selection tool, it does show the face so the meshing progtam must somehow know that it is a filled body but i just doesn't let me select the face... on the other side of the pipe i can select the face with no problem. nIf you have any other ideas, I'd be happy to here about them. n

      When you check for selecting the face, do you mean it turns green? If so, in DesignModeler go to Tools-Optionsnand set to highlight both sides. The single side is default for reasons that the Mechanical team understand: for the rest of us it's an annoyance which is fixed by changing the behaviour. n
