Can fluent tet mesh be converted into Polyhedral mesh in CCM?
Hi everybody
I have conducted simulation in FLUENT previously and now I want to simulate in STAR-CCM with Polyhedral mesh. Since the geometry contains many parts and its tedious if I generate the mesh from the beginning, so I was wondering, if there is a way that I can vonvert the existing FLUENT mesh(.msh file) into Polyhedral mesh in ICEM or in CCM+? Thank you all very much |

You can't convert a mesh into a polyhedral mesh using STAR-CCM+.

Then I have to try other methods. At least I won't dewell on this idea any more. Thank you very much! |
Import your tet mesh (.msh or .cas) file to CCM. Extract the boundary surfaces from the representation and then create the poly in CCM. Otherwise you can use same tet mesh for the solution also. But converting directly is not possible.

What you said is right what I have imagined! So it is possible to extract shell mesh from 3D .msh file and use it to regenerate mesh in CCM? Can you tell me how to conduct the extract operation? Because I have looked through the tabs and did't find any thing. Thank you very much! |

First import the .msh to CCM and then go to representation node and right click on volume mesh. You will find extract boundary surfaces node there. Do that. Then extra node will be created below it named as exracted surface. The region name will appear, right click on it and export it (.dbs) . Then import this as surface mesh and you will have the extracted geometry. |

It worked! It is exactally what I have imagined to achieve. Can't express my appreciation enough. Thank you so much. Best Wishes! |
