Hallo, every
I'm new with CFD, working on a cyclone Simulation. Right now I am generating a mesh with ICEM, actually floowing a tutorial but with some Adaptions because of differences of the geometry. But right now my mesh Quality below 0.5 are in These regions: in Picture (attachment) with green Color (mainly the inflow Region, high skewness and the contact Region of cylinders). could anyone help me with the modification? what could i do to improve the Quality? Thank you so much Comingdaytime |

Hello Zhiyi,
your cylone inlet region contains a degenerated block. That's the reason for low mesh quality in that part. This kind of the geometry is similar to another popular question, how to mesh a volute in a centrifugal pump. Without explaining much, check page 96 in the following document! https://docs.google.com/file/d/0ByIL...BQT3pQMjQ/edit This can give you a few ideas how to improve the blocking. The inner regions with bad mesh quality are difficult to see. May add some more pictures of those details. with regards, Sebastian |

Hello,
It seems that there are some skewed mesh around the sharp edges. I think it's better to use hybrid mesh in this situation. (tet mesh for sharp edge region and hex for another region) regards, JM |
