Export Fluid Interface Data

Please login with a confirmed email address before reporting spam

I have been working through using Multiphysics to calculate droplet shape within a microfluidic channel, much like the following example:

www.comsol.com/showroom/gallery/1994/

The model is: "Two-Phase Flow, Laminar, Level Set"

What I would like to do now is to study mass transfer between the droplet and the surrounding fluid, in a "long" channel. One way I would think about approaching this is to look at one droplet in a moving reference frame. i would like the geometry of the interface to be as correct as possible. What I would like to do is to export the fluid interface data from this simulation and create a new simulation where this fluid boundary is fixed, so I can define boundary conditions on it, while still solving for the velocity profile in the surrounding liquid.

Any suggestions on how to go about exporting the fluid interface data (i.e. level set function = 0.5)?
