Cylinder with fluid

pascal · September 7, 2006, 07:45

Hi. I am new to open foam and I have really less experience with CFD. my problem is that I have a cylinder filled with gas. a fluid is running down the wall of this cylinder an is going to fill it. inside this big cylinder is a smaller one, and when the fuid has risen high enough its gonne run in this smaller cylinder.
so can u give me a hint which case I should use and what I have to consider for my problem?I think this should be no hard problem, but as I said, I never worked in this way before. thank you,

I have created the mesh with netgen and then converted it to openFoam. the top of the cylinder is my inlet. the other patches are walls.

Hello,

You have a fluid (liquid?) injected into domain filled with gas. I think interFOAM should do the trick. it uses the VOF method to capture the interface.
