Hi
Have you tried to look at the model library (update it before to have them all, in compact mode it's quicker) search for "drop", or "level set"

Good luck

When I run the droplet breakup model it says "Out of memory during assembly" (both phase initialisation and time dependent studies)
Anyway , more importantly this example considered emulsions
I really could not make out much about individual droplets. can I put a single individual droplet ? like the paper I attached to the first post?
suppose i want to do a simple geometry with a rectangle and a ellipse. so that we have in 2D, a structure where the droplet touches the micro channel. I have made different structures like that. but could not make individual electrodes with electrostatic charges so that I can see the effect of potential on the droplet thorough change in surface tension
also if I try to solve with the edge of the a sphere on a layer of any material, it can not be solved. It says "surfaces intersecting"
how can I change the meshing so that I can solve those scenarios? or Am I wrong in the whole approach ?

Hi
you have myny questions and I do not knowanswers for all, but the issue with he meshing of a dropplet aas a circle / spehere intersecting with a line / plane triggers my mind. As you get silver faces/planes when you get a tangent intersection like that of a circle / sphere and a line plane. Thise give singular point contacts, one should really adjust the geoemtries such that they have aclean (within the geometric resolution) defined common boundary.

I am trying to recreate the droplet breakup model, and I too am getting the "Out of memory" error.
I don't understand the error. COMSOL says I'm only using 371MB out of 400MB, and I've used much more than 400MB in other models.

Hi!
I require the model used in the following paper.
www.comsol.com/paper/5283
So I was wondering If you were able to replicate it or able to find it. If so, please share.
