Change Free Surface Flags over time

Hello everyone.

I have been using Palabos quite a bit and I have started to use the FreeSurface model for my research. I would like to model a “melting” wall, where over time the walls of the domain will change into fluid. However, changing just the fluid flag, volume fraction, cell density, and dynamics of the cell do not work, more specifically the fluid does not flow throughout the domain. I have been able to change the volume fraction and the other parameters above using a data processor, but the fluid is stagnant and does not flow into the empty cells.

Has anyone ever changed the fluid flag successfully inside the time loop?

Thank you,
