LIGGGHTS - Vibration Effect on Particles Stuck on Wall

I am trying to simulate an ultrasound vibration effect on stuck particles on wall by using "fix move all move/mesh mesh cad1 wiggle" command. I know this line is not creating a wave vibration but still I would like to see if "wiggle" command can remove the particles from the wall if I use low amplitude with very high frequency. I use cohesion model to stick particles on the wall.

However, the particles are not being removed from the wall with this vibration effect. My question is, am I working on something that LIGGGHTS has some limitations or should I use a different command to vibrate my walls. Or maybe my model is wrong?

Note: My particles are very small so I needed to decrease the volume limit to 1e-15.

I am sharing my input file:
