Hello everyone,
i'm trying to simulate interior acoustics with Optistruct using coupled frequency response analysis. In my model i have multiple surfaces with different materials assigned. I know the sound absorption coefficient for those surfaces but i don't know how or if it's possible to model this in optistruct. So my questions are:
- Is it possible to assign a sound absorption coefficient to different Materials/Properties/Elements?
- If i can't assign a sound absorption coefficient directly, is there any other way to achieve sound damping in optistruct?
- If it's possible, is it also possible to do that frequency dependent?
Thank you all in advance
