Agility, Permeable and SemiPermeable Membranes

In the Ripple Tank simulator there are two kinds of boundaries available - edit Walls, edit Medium. I think but do not know the edit Medium changes the density of the fluid through which the waves move. I am taking the Medium boundaries as semipermeable membranes. Walls with Fixed Edges set are rigid and do not allow wave energy to pass through.

Note the energy source is outside rather than inside the nTube represented. 

1. Set Up

2. Set up 1 running for a bit.

3. Set up 2 in 3d view.

4. Set up 2. Note: Walls have been added to the boundary.

5. Set up 2 running for a bit.

6. 3d view of number 5
