CFX extruded 2D mesh...!

Hi to all,
I have to mesh a 3d very thin geometry. I tried every types of meshing in CFX and I decided to use 2d extruded mesh. It is the best for me. But I have a problem about extruded periodic pair!!! I have to enter the different periodic pairs in only one location according to the program. In my geometry I have a thin body in the big one. To provide periodic pairs I splitted it to 3 body(up pair; middle pair which is the same level with the inner body; down pair).I hope I could explain my problem and please I need your help!!! Thanks...! |

Why don´t u build a 3d geometry with a thin lenght on z-direction, instead of making only a 2D?

Hi again,
I did volume mesh with advancing front and ınflation 3d method. But my inner body has 0.1 mm thickness so I used very small face spacing. but it gave me plenty numbers of tethedral elemans. I don't want it. extruded 2d mesh will give me what I want, I suppose! I have already splitted my geometry to 3 body on z direction which one has 0.1 mm thickness as the same level with inner body to provide periodicity. Mr.Brito, I suppose that my first method is the same with your opinion,but if I'm wrong could you please explain it to me...! |

Hi,
Can you post an image of the geometry? Glenn Horrocks |

My volume (air) has totaly 2.1 mm thickness. In the middle, I have a 0.1 mm solid body. I splitted my volume to 3 part 1 mm -0.1 mm -1 mm (thicknesses) on z direction. I did it to have periodic pairs. Air is covering the solid and to use 2d extruded mesh ı have to have periodic pairs. But my problem is when ı finish the mesh, 0.1 mm solid is looking as it has 1 mm thickness and it is becoming apart from the air( I mean I'm having a meaningless blank in the volume).
I'm sorry for not sending any image....! |
