Hi, everyone

I'm learning CFX-Build now and having some problems

1.I'm trying to set a thin surface in CFX-Build. But I don't know how. I created a surface and named it as wall1. But it seemed invalid. Air flows through it just as there isn't any thin surface.

2.I want to calculate fluid flowing around an object. I created a solid. But flow still occurs in the solid region. I don't know why.

Thanks.

Hi,
You must be sure that there's an interface (interblock boundary) between the two blocks. If you're still in trouble I can send you a simple example.
Good luck, cfd guy

I've already tried this. It works. Thanks.
