How to use Gambit create "Mesh Edge" for circle o&#1

jpopsurfer

Hi,
Does anyone knows how to mesh edge for circle, oval or irregular boundary using Gambit?
Thank...

你是要画圆形或者椭圆形的面网格吧？不仅是边吧？

jpopsurfer

yes..
I know how to mesh edge and mesh face for rectangle boundary..
but I need to mesh edge and mesh face a human heart boundary.
Can anyone help me please?
Thank you.[br][br][以下内容由 jpopsurfer 在 2008年04月16日 10:57pm 时添加] [br]

你遇到什么困难了吗？用Gambit做面网格是很简单的。

newanda

你可以用非结构的网格来画不规则面上的网格。
比如，在生成面网格时，Elements项选Tri或者Quad，Type项选Pave。试情况而定吧。

直接mesh面

You mean no need to mesh edge for a 2D human heart?
Just Mesh Face?
Under Elements, I set Quad/Tri and under Type, I set to Pave.
What about interval count? I set to 5 and click apply, but the meshing is very very slow...
Pls help me.. Thank you.

You may choose Tri+Pave instead, as the interval count, just set to the number you feel enough.

I heard that for laminar flow, I need to mesh the face as Quad.. Is this correct?
May I asked how many interval counts is enough?

interval counts是根据你的流场而定的
先可以设定一个较小的值，画好网格计算看看边界处相应的y＋值，小于100就可以接受，不行就调整interval counts大一些

cupidvenus

interval counts的设置与你的直径有关，不宜设得太小，可先设为直径的1/10试试

I am using interval counts of 10 now. The meshing takes a long time when I set to Quad/Tri and Pave. Am I doing the right thing? I need to import into Fluent later.
