HELP

[Lucas Soffer]

hi, 

i'm really new to basilisk and i must admit im a little bit overwhelmed with all of it. i'm trying to simulate a droplet of water only a few microns thick laying on the surface of a hydrophobic material. the idea is to find the equilibrium shape of this droplet of water. if someone could point me in the right direction of how to start this or could write some example codes i would be super grateful!! thanks

[Lucas Soffer]

if someone could help me define a surface for which the droplet can lay on that would be of great help! thanks

not sure, if this would help:

Hallo Lucas,

In addition to Shariar's response, a perfect hydrophobic bottom-surface boundary condition (i.e. 180 degrees contact angle) may be conveniently approximated like so:

f[bottom] = 0.

where f is the volume fraction field of the wet phase in the simulation.

An example that passes at least a visual test is presented here:

How to find equilibrium solutions is another topic...

I hope it HELPs

Hallo again,

I got a bit carried away by this topic. The result may serve you as an example:
