Hi PF!
I am confused about solving PDE's using a similarity solution. How do we come up with the similarity variable? Is it scaling or lucky guesses?
I've read several papers on it but haven't found the reasons on why they use the variables they do for the similarity to work. Any advice from you would be great!
Thanks!
