Click For Summary
COMSOL is perceived to provide unrealistic solutions for time-domain wave problems, particularly in mechanical waves and wave equations. In contrast, its performance in the frequency domain is considered more reliable for wave simulations. Users are encouraged to run benchmark problems to validate their simulations, although one participant reports consistent inaccuracies in time-domain results. A quick test of a 2D solid's elastic vibration problem yielded incorrect solutions. This raises concerns about the software's effectiveness for realistic wave problem simulations.

COMSOL gives me the impression that it always gives unrealistic solutions in time domain for wave problems, say mechanical waves or simply solutions of a wave equation. In frequency domain, COMSOL works better for wave problems. Anybody agrees?

That’s interesting. Have you tried running some benchmark problems or verifying these simulations in some other way ?

not really though. one can spend 5mins running an elastic vibration problem of a 2D solid in time domain, and there's never correct solutions.
 
Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
