AI Thread Summary
The discussion focuses on modeling a micro-cantilever resonating in water to assess the impact of water damping on the quality factor. The user attempted to use the fluid-structure interaction module in COMSOL but found no change in the quality factor, suggesting the model behaves as if in a vacuum. Guidance is sought on selecting the appropriate application modes in COMSOL for this scenario. There is also interest in the potential application to macroscopic cantilevers. The thread highlights challenges in accurately simulating fluid effects on structural dynamics.

I am trying to model a micro-cantilever resonating in water, in order to measure the decrease in the quality factor due to water damping. I tried fluid-structure interaction module but observed no change in quality factor. It worked as if the medium is vacuum.
Can anyone guide me to select the appropriate application modes in COMSOL?
Thanks in advance..

I don't know if you found the answer to this... but I would be interested If you have. I kind of am more interested in a macroscopic cantilever, but I am curious nonetheless...

Thread 'I need a concave mirror with a focal length length of 150 feet'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
