Karthick Guest Posts: n/a	Hello all I am using dynamic mesh model which simulates the movement of shuttle due to pressure difference across either sides. But the problem is I declared the piston face as wall, where I am specifying the velocity. Also I need two walls(piston entry and exit faces where the pressure has to be measured). This difference in pressure is converted to velocity of piston. So I have to declare two boundary conditions to a particular edge. But Gambit is not allowing me to do that. Either of one is possible in it. Is it possible by anyway to declare 2 BC to a particular entity? Regards Karthick
