Applying the Dirichlet boundary condition on moving free surface
 

Hello Foamers,

This is my first thread, and I am using interFoam solver to solve the multi-phase problems.

I have a simple question regarding how to apply the Dirichlet boundary condition on moving interface in each time step. I know how to set the Dirichlet boundary condition as an initial BCs but do not how to apply the Dirichlet boundary condition continuously during the simulations.

I do hope you can give me some suggestion on this problem.

Many thanks,
Xia
