Acoustic simulation

Thanh Tung Ho · March 26

Hello,

Currently I'm researching into sound and noise simulation in automotives and I have some questions that I hope the experts here answer.

1. Can the Optistruct solver be used to simulate sound and noise? If so, can you share with me how to build the model and set up the problem? I have searched a lot on the internet but have not found any acoustic simulation problems using optistruct.

2. Is it possible to model sound-absorbing materials (eg: fiberglass, Pu foam,...) on hypermesh? If so, which image card to use in the materials section to simulate those materials and how to set the parameters there?

Thank you.
