Creating the model structure
Edit Diffusion_Down. Enter the same expression “D/(R * dx2)”, where D has the same properties as in the previous model:
|D||Parameter||m2 year-1||Diffusion coefficient||1|
Assign the same expression to Diffusion_Up and Diffusion_Out.
Run simulations with different values for N. How many discretizations are needed to make the curve converge?
Change the Advection Velocity v to 10 m year-1. As the total depth of the media is 10m, the transport should now occur in a much shorter time span than before. Change the end time of the simulation to a lower value, say 3 years.
How many discretizations are now needed to make the curve converge?
