🤽♂️ Drop the ball in the water
This is a simulation of a ball falling into water. The effect of the water is represented by #VDLOAD and #VUAMP subroutines and a sensor.
The square which represents the surface is there for visualization only. The sensor monitors the displacement of the cg of the ball. VDLOAD applies a pressure that depends on the distance of the load point below the surface. VUAMP is used with the loads STAGP and VP.
VUAMP reads the cg and sets the amplitude to 1 when it is below the surface and 0 when it is above the surface. VDLOAD doesn't need the sensor because coordinates are passed into it. VP is used to provide a little damping and make the simulation appear more realistic.
The density of the ball material is a little less than the density of the water.
