combining acoustic with laminar flow

Please login with a confirmed email address before reporting spam

Hi all,
did anybody simulated wind speed/direction impact on acoustic field?
combining laminar flow with pressure acoustics does not create multiphysics node.
Anybody have an idea?

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.
