I hawe a multiphase flow problem, I need to compute the following (1) interface Area between air and water in figure 1 , and (2) the distance marked as R in figure 2. Someone please help me in computing these

figure 1: Screenshot 2020-06-27 at 10.43.32 AM.jpg

figure 2: Screenshot 2020-06-27 at 10.46.08 AM.jpg

Thanks.

Hi,

You could:

1) make a iso-surface of VOF=0.5 for air.
2) cut the iso-surface with iso-clip with VOF water=1e-3 to 1.
3) use report->surface->area -> of the clipped surface, to get the area.
4) use report->surface ->min/max radial distance to get the radial extend.

I think this will give you what you want, without resorting to UDF programming.
