I'm creating a mesh which ill use in fluentbut at the entrance and exits my mesh goes wild and i dont know how to fix it, can someone pls help me. Im using ogrid and when i use my mesh is good in all places except entrance/exit. skewnees is awful and it looks like this [img=http://imageshack.us/scaled/thumb/28/3y1.png] [img=http://imageshack.us/scaled/thumb/21/wjjj.png] mb this should be moved to ANSYS Meshing & Geometry |

there is nothing better than a video to explain this. but i can't install a mkv codec due to privileges. i will try to do that from home. meanwhile i did the necessary split. and merge some vertex together, and o-grid were the last... look at the tutorial "3d pipe junction" it is same blocking strategy, you can start from that one to understand

@ Ali : Here I have compared two types of T-Junctions blocking in ICEM CFD. Models are M1 and M2. The blocking method of M2 is yours.
@EugenZ: Here is video tutorial and all other files for your reference. PS. I was using M1 blocking method for M2 and but it turns out to be that Ali's method is better. Follow this link please : http://www.cfd-online.com/Forums/ans...-icem-cfd.html |
