I am trying to convert the application model "Piezoelectric Energy Harvester"(www.comsol.com/model/piezoelectric-energy-harvester-21421) into a 3-D model to apply the frequency response study set-up to some relevant research. I have encountered a lot of issues with making the computation to work, however, so I am wondering if there is a glaring difference between the working 2-D model and a would-be 3-D model that I overlooked.
I pretty much just made all of line boundaries that defined the interfaces into respective surfaces in the 3-D model, and am using a free tetrahedral mesh. Other than that, just about everything else has remained the same, including the circuit node numberings.
The issues have ranged from an absurd amount of computation time that my computer couldn't handle, to the return of completely static results (i.e. the stress result for each frequency is just a green image of the original beam).
Any thoughts as to what I could be missing or what could help with making it work would be greatly appreciated.
Thank you for your time.
