Visible Gemometry to view the inside flow countour
 

Hi,

I have a square box (3D) and I would like to view the flow of gas inside the box . The inlet of the gas is at the bottom of the box with a small square as inlet. What can I do to make only the gas is visible inside the box?

You can use pathline in display tab. also you can make a surface and show results on the surface.

Thanks for the reply . The pathline dispay is kind of messy. The gas has different behaviour at different planes, I would like to show it in a full geometry (square box). Any alternative that I can do to make the box invisible and look into the inside gas?
