Hello, I am using Tetra + prism method to mesh fluid domain around a turbine blade.I have got good elements except around the tip and the root(see pics). I tried to smooth(first tetra then prism and tetra together),but even worse quality appeared.
Can anybody share any experience about this kind of cases? What is the difference between tick on and tick off the Laplace smooth function?I always got worse quality with it on. Or the bad elements could be due to other factors? Any advice is welcome. |

Hello Far,
Thanks for your reply. It is difficult to get a good quality using tetra+prisms while the boundary layer mesh goes too fine. I have also tried ICEM hexa, using o block +split at the trailing edge, but resulted bad cells again around the sharp trailing edge .I have seen your video on youtube"wing with sharp trailing edge". I must missed something. I do not know if you could look at my problem here. |

Yes tried
but it seemed that it cannot be converted. "number of degenerate corner !=2" |

I realised that this is not a wedge block. ..it has 8 corners so cannot be converted
