How to set oscillating pressure boundary condition

acoustic · August 28, 2009, 02:52

Hi everyone,

I would like to simulate the flow inside a tube having one closed end and the other end is driven by a loud speaker.

The speaker creates an oscillating pressure (and velocity) which will have an effect on the acoustic field inside the tube.

so to be clear: which boundary type shall I choose in GAMBIT for the speaker end. (the other boundaries are "wall" type).

Thank you in advance for your help
