Visualize air movement in speakers

Nastran in cad does however simulate radiation, If you can get your head around it that is. When i have ill upload an image. 

I could steer you in a direction to run valid simulations using your software, but i wont. I wont because i already know, that without proper physical understanding of what you are doing, you will never, ever be able to present simulations of what is going on. There is tools with perfectly applicable results out there already, such as indeed ABEC (Bem, not FEM like your model). But even then, the knowledge and experience needed to present results that represent the physical world, is not something you can learn today and be an expert in tomorrow.

There is already so much misinformation on here, please dont expand it by posting random simulations and presenting them as valid. Either that, or go off to learn computational fluid dynamics and come back when you understand it.

please note, this is not a personal attack on you or anything so apoligies in advance if thats what  it reads like, but misinformation in an already not so very sceintific place, is the last thing i need to see here.

CFD is merely a collecting term for computational fluid dynamical simulations. It can include computational Aeroacoustics, or whatver you like to call it.

My point is, that running a simulation without putting in the correct equations, will never result in a correct answer. Lets say i want to calculate the velocity of a car after 10 seconds if it accelerates at a constant rate. If i simulate this with an equation that models gravity, the results will never be correct. Do you understand what i mean?

To exagerate a bit just for the fun of it, What you have done is put a car in a wind tunnel, filled it with lava and fired it up at flow speeds of a million miles an hour, to see if the wind in the tunnel is affected by the presence of the car, when you actually want to know how the car will influence sound passing through the windtunnel, when no mean flow at all is present.

Anyone have an y experience with comsol 4.4? There is what might be a pretty good tutorial for 3d simulation of aero and pressure acoustics in comsol but until i understand more about i cant say for sure.
