Hi guys;

I am using interFoam to study microchannel flows, droplet fragmentation etc. I would like to know how can I get the volume of droplet fragmented? For example as shown in fig1.jpg.

I see some papers such as in "Benchmark numerical simulations of segmented two-phase flows in microchannels using the Volume of Fluid method" who used interFOAM and probably paraview as a post-process tool. Is there a function in paraview that can do the job?

Thanks;

Hi Saideep

I don't think there is a simple way to automate it. And depending on how much data you need, it may be easiest just to manually find the volume using Paraview. I would use a box to cut out the region wherein you find the blob, then cut by the scalar value of alpha, integrate over the remaining region to extract the volume of the blob. You could even allow this run over the whole simulation and take the maximum volume which will be period with the blobs being formed, if they are similar every time.
