Hi every one
Excuse me if my English is not good.
I am beginner in cfx. i simulated cylinder and piston. figure below indicates the geometry and meshes. For simulating piston I used mesh deformation feature and analyze type is transient. but when solving error below occured.
If possible, please guide me.
Thanks a lot

You have defined the piston motion as a constant - 2[m]. This means the mesh will jump to this position in the first time step and stop there. This is wrong, you have to write the displacement as a function of time, maybe a sin() function or something so the piston can move gradually as a function of time from the starting location to the finish location.
