Automatic geometry preparation for hex mesh and circle curve splitting

Hello.
I am learning ICEM CFD. And watch one interesting video (http://compteacher.ru/engineering/55...obuchenie.html) – video №4 (L-type geometry with 4 inlets). Author of this video make hex mesh very fast and easy. But one thing is not clear for me. When he starts work with blocking, he has a lot of predefined points on geometry. On circle curves there are 4 points like on figure №2 (not like on figure №1). Also he said that this point can be automatically calculated base on the feature angle and tolerance (if I hear correctly). So my question is how we can split circle curves to 4 arc curves automatically (like in figure №2)? And how prepare geometry for hex meshing – add additional points - also in automatic? I find some answers, but they need a lot of work to do 1. In ICEM make on circle curve 4 points and split this curve by them. (allot work on every curve) 2. In ANSYS DesignModeler – split edge command + split type: split by N=8 (this variant is a good one) It will be cool to do this preparation in automatic not by hand |

under geometry tab, click on create point ---» select "paramater along a curve". if you give it 0.5, the point will be created half way the curve... use 0.25 and .75 to get what you want.

Thanks for answer.
But I’m mentioned this variant (see my answer №1). To deal with this you should create 4 points and than splits. A lot of hand work, not cool! Using DesignModeler is much faster, but not really automatic. |
