I work with Acoustic module in Acoustic-Solid interation Frequency Domain. I would like to get frequency responses of simple bodies like cylinder etc. To do this I set the point at the surface of the body and put it under planar acoustic wave with certain amplitude at the frequency range from low to high frequencies.
So, which parameter I should choose after computation to get this response as a plot?
As I can see, I have several possibilities:
- Displacement field (X, Y, Z components);
- Displacement amplitude (X, Y, Z components);
- Displacement RMS;
- Total displacement
Could you give me some strict math definitions of these parameters or just a link where I could find this information? I would like to understand how to connect this parameters with mechanical propierties and geometry of modeled bodies.
I'm sorry if such topic already exists. Unfortunately, I didn't find clear information about it on this forum and in Comsol's help.
