Meshing problems
5 Attachment(s)
Hello everyone. Sorry for a bad english, but i try to explain my problem.
I am meshing journal bearing with oil inlet, and all of my attemps unsuccessful. I had to slice the geometry because of poor mesh quality. 1-thin film 2-inlet pipe and now i have a problem with connection of 2 fluid zones I tryed recomendations from this thead but it doesn't help http://www.cfd-online.com/Forums/flu...tml#post278469 Could you tell me what i should to do. Maybe i have missed something important. |
your problem description wasn't clear.
Please upload your case file if possible. |
Hi Aleaxander,
If I am not wrong, you have created two separate volume meshes for thin-film & inlet-pipe and trying to define a non-conformal interface between the two volume meshes/zones. What is the problem you are facing in defining the non-conformal interface. Does Fluent gives some error message? Or you don't see fluid flowing from inlet pipe into thin film region? Having said that, creating a single connected / conformal mesh is possible for your case, if you are using Multi-block approach. Happy Learning!!! Praveen Kumar R |

Hi Aleaxander,
I examined the case file, the interface looks just fine. When tried to run the case setup as it is, I observed a pathline similar to what you got. i.e., flow not going from inlet zone to film zone. But I was not sure whether the issue is with interface or not. So, I tried running the case with velocity inlet (0.25 m/s randomly taken this value) and its working fine. Please see the attached picture. As I said, the interface looks just fine. Please revisit pressure values at the boundaries.... All d best!!! Happy Learning!!! Praveen Kumar R |

I will try to improve my model so maybe there where any questions=) |
