Dynamic mesh problem
 

Hello all

I am using dynamic mesh model for running my piston-cylinder problem. Can anyone tell me the following?

1. I can see the motion in "Mesh motion" panel. But when I try to iterate it, the motion is not happening. what may be the reason?

2. Through one face, fluid is entering the domain(pressure-inlet) and pushing the piston to the other side. What boundary condition I have to give to the other face?

Anybody please help....

Regards Karthick

Try to reduce the time step size and increase the number of time step in order to reduce the movement of the moving boundary at each time step. This's what I did when I got this problem.
