Dear all,

I am new in CFD simulation and this is my first post in this forum.

I am modeling a fluid viscous damper in 2D axisymmetric, I used a dynamic mesh to have a sinusoidal displacement of the piston, my model does not contain inlet and outlet.

After the calculation, I noticed that the variation of pressure is in the room 2 while that of the room 1 remains almost zero along the simulation, and it seems illogical to me.

I don't know exactly where is the problem.

Please take a look at the screenshot of my model attached to this post.

I really need your help.
thanks in advance!
