                            Hi
Have you studies this application library example ?

                                                    Dear  Ivar,
the >Ultrasound> is not available in the 5.2 :(
if I try with pressure acoustic would it be fine?

                                                    Hello
you are right its a new feature of 5.2a I see.
Normally you need the transport part that has been added to the Convected wave equation in 5.2a, you might write it out yourself, but there a quite some equations, probably its easier to upgrade if you have the cash ;(
I'm a happy user with a boss accepting to pay the maintenance and the upgrades. And at the speed COMSOL adds new features it's worth it, at least for an industrial approach.

Good luck
