interTrackFoam solver for axisymmetric droplet simulation

kal1943335 · February 1, 2017, 11:14

Dear All,

I'm trying to simulate movement of a droplet on a solid surface due to thermo-capillary flows. I came across this interTrackFoam solver, which is capable of simulating both normal and tangential surface tension components. So I spent some time on that solver in openFoam 4.0 extended version.

I have few questions regarding this solver.

1. Contact angle - my problem needs to have a constant contact angle boundary condition for the interface. I'm not sure how this solver handles such situation.
2. possibility of having an axi-symmetric geometry.

Please let me know if you have experience in dealing with such problems in interTrackFoam.
Thanking you in advance.

Hi Kalpana,
Have you get any progress about this issue?

No. I couldn't make it work for a droplet. The mesh I made for a droplet was not good enough to have mesh movement. And for my problem, the movement was too much for the mesh to handle.
