Hi all

I am looking to purchase a hydraulics surge analysis software for my
company, and have narrowed it down to Flowmaster and Amesim. One uses
Method of Characteristcs and the other Bond Graph method... and of
course both say their method is better :)

Does anyone know the advantages and disadvantages of each? and any
feedback on the software mentioned

Thank you in advance
