This package contains the physical model of this simulations.

The origin of the model coordinate system is at the upper left corner of the canvas. +x is to the right, +y is down.

The local origin of the fluid is at its center. The fluid must flow left-to-right or right-to-left.

The local origin of the laser is at the center of the trap. The laser must point up; the model does not support arbitrary orientation.

The local origin of the bead is at its center.
