Dear all
I have made a 3d mesh which has 2 periodic faces. When i open the .msh file fluent has these two faces as wall. How can i set them as periodic? At boundary conditions i dont find the boundary: periodic and the "periodic conditions" of "Define" menu is not enable. What could i do for that? Thanks.. |

Hi!
You have to do with a TUI command: /mesh/modify-zones/make-periodic Regards, -Edu- |

If you're using FLUENT 13 then change the boundarys of the 2 faces to interfaces and then under the tab Mesh Interface you can define your periodic boundary

@delaneyluke: I tend to use this method, whenever the periodic surfaces have the different mesh distribution.
@Edu-R: This method only works, when the mesh is exactly the same (I am not talking about similar) node to node on periodic planes. |

kostaspan, as Far says, if you don't have the same mesh (or at least with a difference lower than "matching tolerance" parameter), you have to use the method they say. Regards |

Just wanted to share my experience, no hard feeling. Afterall this is brain storming. Your method is my favourite one, and I use whenever I can. |
