Acoustic FEA
Acoustic FEA
(OP)
Hello,
I am seeking information about an Acoustic FEA problem. I want to simulate a sound wave traveling into a group of very thin vertical columns (actually polymer fibers). These fibers are what you would find in something like a carpet. I would only model 3 or 4 fibers to start with. I need to see if the sound wave is absorbed by the fibers or if the sound wave is slowed down by interation with the fibers. I will later change the diameter of the fibers to see that effect. I am attaching a jpeg to illustrate this problem. Some things I need to know include; what FEA software could do this simulation, is this feasible, should I use ALE methods? Thanks in advance.

Is this for school?
