Aspect ratio calculator program shown in the CG youtube tutorial videos.
Copy the executable into the directory containing your ratio files then run the program as shown in the tutorial video. Fill in the parameters from your simulations when requested and it will generate the following files:
x_processed.csv (outer loop parameter on X vs. inner loop parameter on Y - for each value of outer loop parameter) x_transposed.csv (inner loop parameter on X vs. outer loop parameter on Y - for each value of inner loop parameter) 3d(x)-(y).csv (3d plot for each length combination from your chosen indices).
