Hello,
I have to simulate the freezing of a water droplet on a cold surface.
My goal is to simulate the conical shape of the drop. I have a few questions
1- How can I model the volume change of a sessile droplet?
2- For 3D simulation, the first geometry should be a sphere shape.
4- How to consider boundary conditions?
3- Is it needed to change the solver by UDF functions?
4- Is it necessary to consider dynamic mesh?
Could you assist me in modelling the solidification of a sessile water droplet on a cold surface by considering volume change?

Have a look at VOF and the solidification/melting model in Fluent. No need for deforming mesh, but you may want to review dynamic adaption. And Patch to get the initial droplet.
