Hello everyone,
I'm having an issue with unstructured mesh in ICEM given that I receive the error of uncovered faces. While I know that in hexa case I have to associate edges with curves, in this case I have no idea how to fix it. If I let the software fix the problem, what I obtain it's just a set of tetra sizes randomly placed in my domain. I enclose herewith my mesh before running the uncovered faces check Thanks in advance for your help |

uncovered face, general means you have un-associated edge and curve.
so recheck it again. could you pease upload your project file. |

I actually know that and know how to fix in hexa mesh.
Instead, I have no idea how to approach the problem in tetra mesh. I tried to upload the file but, even zipped, doesn't get smaller than 2MB. My question is: do I have to create all the blocks as in the hexa case? |

1 repair the geometry 2 set the size distribution 3. generate the mesh. but from you picture, i met some simillary problem before, i suggest you to change the grid generation method . it seems that you use a autoblock way, try other method |

Both Delaunay and Advancing front give me no proper solution.
I also managed to upload the .prj file |

I managed to solve the previous problem but I still encounter some issues when trying to open the file in Fluent.
Once I load it I get the message of uncovered faces although the check in ICEM doesn't show any failure. |
