Sure, here is a link to the code: mountain-flows/testkata.py at main · Mgomes96/mountain-flows · GitHub
You shouldn’t need to download any packages in order for it to work. The plotly part is only a small part in in the end of the code. There is a line towards the end which reads: “#Uncommenting the next line causes the results to change dramatically” which if you uncomment results in different results even with the vector fields remaining the same.
Thank you!
