Dear Shuangxing Du;

For analyzing the hydrodynamic response of the piston:

The piston’s point mass is positioned at -665 mm. A regular wave was defined with an amplitude of 1 mm, a frequency of 10 rad/s, and a wavelength of 616.16 mm. According to theory, the wave effect should reach a depth equal to half the wavelength.

However, the piston is not remaining stable underwater. What could be causing this instability? By the way, the water depth is 70000 mm.
