1D
 

Hi, everybody,

I am trying to simulate the 1D sound distribution in a tube with one end closed, and the other driven by a piston. The tube is filled with air. I would like to use the Godunove scheme, but I am not sure how to deal with the two boundaries as the method that I used in the code caused strong numerical oscillation. Could you please give me some ideas or recommend books for me to deal with it?

Thanks A Lot!
