Choosing the boundary coundition
 

Hey Foamers!

I am runing the damBreak case with different turbulence models. But, I got stuck in the choice of the appropriate boundary conditions and their values, I just accepted the default values. Can anyone help me in how I choose the BC and their values.

I need to simulate the case of the removal of the tank with an accleration 0.1 m/s2. Does any body know how to implement a boundary condition in which the tank wall has an acceleration of 0.1 m/s2 just for a short period of time of the begining of the simulation and then the boundary condition changes to fixedValue for the rest of the simulation ?

Any help would be very much appreciated!!
