 ## Lid-driven cavity
-After running the lid-drive cavity problem, the simulation will output two files (`NeonMultiResLBM_####_Y.dat`, `NeonMultiResLBM_####_X.dat`) which can be used to reproduce Figure 7 in the paper. To reproduce the figure, pass these two files to this [python script](/scripts/plot.py).
