Filling by capillary forces
Hi, I want to simulate the dynamics of filling of a channel by capillary forces. I thougth about modelling the fluid front by the FREE-SURFACE method of FIDAP.

But on the three-phase-line the nodes should be movable in the filling direction to get a fill, on the other hand all nodes at the channel wall should be fixed to satisfy the no-slip boundary to get a correct velocity profile.

Does anybody know a solution or did a similar simulation and can give me some tips.

Thanks for your answers, Jochen
