Hi rwoolhou,


unfortunately I am still having problems with this boundary condition. Thanks for your continued support.


sharing topology on spaceclaim causes a weird problem in the mesh editor where i am selective body meshing is not being recorded. After doing some searching, I found that I can RMB and clear generated data. After this, I can generate the mesh without seeing the message.


I can walk you through my methodology to see if I can get any hints on what I have been doing wrong, because i cannot even get a solution due to my energy residuals. I do have most of my steps shown in the above messages.


1. spaceclaim: created a domain using enclosure


2. spaceclaim: share topology, hiding solid bodies other than battery fan


3. spaceclaim: share topology ONLY on the battery fan circle


4. mesh: create a contact between battery and fluid domain (bonded-no separation)


5. mesh: select the circle that represents the fan and named selection interior-fan


 6. mesh: body and face sizing (giving me the selective body meshing error after) (at this point a message appears: The selective body meshing is not being recorded, so the meshing may not be persistent on an update. If you want to record the order of the body meshing, please use the Mesh Worksheet to track the meshing steps. Please see Selective Meshing documentation for more details) -> at this point I RMB on mesh, clear generated data and then generate the mesh and the message goes away.)


7. fluent: in cell zone condition: turn the fan body into a fluid type


8. fluent: in boundary conditions: turn the interior-fan into a fan boundary condition


9. fluent: set constant pressure jump


10. fluent: heat source generation terms for battery


11. fluent: inlet temperature and velocity set (this is the HVAC which will add cold air into the container), other conditions set (convection, materials)


12. standard initialization at inlet


13. Run


after 50-100 iterations energy begins to diverge
