Bruno Chareyre proposed the following answer:
>So I plan to use the HarmonicMotionEngine to let the bottom wall of the
aabbWalls vibrate and to use the TriaxialSterssController to keep the
stress of the top wall 14KPa. But that is not useful, because when the
HarmonicMotionEngine runs, all walls of the aabbWalls vibrate. What
should I do to solve this problem?
Hello,
I didn't check the script, but isn't it simply because the frequency is too
low? At "high enough" frequency I cannot imagine that the top wall will follow
the motion of the bottom wall instantaneously since it needs at least the
travel time of the sonic wave to perturbate the pressure on the top wall after
moving the bottom one.
