Simple (macroscopic) Cantilever in a Fluid with COMSOL

AI Thread Summary
To find the eigenfrequencies of a simple cantilever in a fluid using COMSOL, focus on setting up the model with appropriate boundary conditions and material properties. The fluid's influence can be simplified by neglecting viscosity, allowing for a clearer analysis of the cantilever's vibrations. Users express frustration over the complexity of COMSOL examples, which often do not address simpler scenarios like this one. Understanding the software's capabilities in this context can enhance user proficiency. Seeking guidance on this straightforward problem is common among users looking to deepen their knowledge of COMSOL.

So I feel like this should be a simpler problem than most with COMSOL...

I have a simple cantilever (anchored at one end) with a force at some point source which is making it vibrate at some frequency. This is a macroscopic cantilever, so you can ignore viscosity (and most of the other Navier Stokes things). It is in a fluid, say water or air, for now. How can I find the eigenfrequencies, or resonant frequencies of that cantilever in water?

Like I said, it seems as if it should be easy. All the examples that COMSOL provides seem to be of very complex things. It is great that they are showing off their software and all it's power, but I would love to know how to do this to increase my understanding of the software.


Thanks very much to any responses in advance

I'll bump one more time for good measure.
 
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...
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 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
