AI Thread 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.
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
