[General] Water surface profile in OpenFoam dambreak case

kerim · January 29, 2012, 00:59

Dear all!
Can someone help me with my problem? I need to build 3D water surface profile for OpenFoam dambreak case. The picture should be like as in attached file. How can I do that? Any help will be highly appreciated.
Thanks in advance.

Hi karim.

Assuming you have already run the case, you need to open paraview, load the case, make shure that the VoF is loaded (alpha) and then create a contour of 0,5 alpha. Make shure that it is visualized as a surface and there you go.

Hope it helps.

Hi Vieri,
Thank you for your information. I followed to your suggestion but it doesn’t help me. Please see the pictures I received. There are two of them: the first is the alpha surface plot at the end time and the other is the counter plot -isosurface of alpha value 0.5 at the end time. It is not what I am looking for. Any other idea?

You should try the "clip" filter for alpha with a value of 0.5.
