If you didn't realize it, the CMG Tutorial on 1D single-phase flow was also the exact problem we wrote our own Python code for in Assignment 11. With some easy modifications, we can also solve Assignment 13 in CMG. Recall the problem schematic

The easiest way to work this problem in CMG is to work through the tutorial saving your input file as assignment14.dat. Then edit the input file in a text editor and manually change the lines related to grid spacing and permeability. The permeability line should look something like

PERMI  20000 10 100 50 20

In this case, 20000 is the largest permeability value allowed in the "fake" grid block without causing an error in CMG. Edit the line related to grid spacing (keyword: DI IVAR) in an appropriate way as well. Save the input file and run. Remember to run the simulation for 3 days in 1 day increment time steps. Once the program has finished running without error, there should be a file assignment14.out in the run directory. Copy this file into this repository, add, commit, and push to Github for submission.

If you would like to check to see if your solution is correct, run the following commands at the Terminal command line in sequence:
