David Prince presentation: COMSOL (and FEA in general) ... practical examples
History:
- 1st Generation
- 1993-96 David was a Master student at Penn St. (member of the 1st graduating class in Acoustics)
- 1997-99 worked at Jensen and continued learing about FEA in acoustics (working with Bob True)
- 1999-05: Worked at True Technologies simulating lineaer and non-linear models of cones, spiders, motors and panels.
- 2nd Generation
- David starting using COMSOL at Knowles Electronics refining the designs of Hearing Aids
- 3rd Generation
- Working at Community Sound (pro audio) developing phase plugs & horns via COMSOL simulations
- PSS - cone, motor and spider designs.
COMSOL works great for Material Property Analysis
