Completed the sliding plates assignment.
Assignment: Simulate the vertical velocity profile of a liquid between two infinitely long plates separated by 40mm. The bottom plate remains fixed, but the top plates begins moving at a constant 40m/s in the +x direction. Using the explicit finite difference method.

Visual python makes it so easy to make a nice graphical simulation. I use arrows along the profile that change from blue to red as they increase in length to show the velocity.
