I have over 20 years experience as new product development/design engineer at General Electric and hold a Ph.D. in mechanical engineering. I can provide both mechanical & thermal FEA modeling as well as develop separate analytically models such finite difference schemes, node resistance network models using spread sheet or other tools such EES (Engineering Equation Solver). I also offer traditional max stack and statistical tolerance analysis, I have extensive experience with hyper precision mechanical design as part of my daily work ($35/hr for tolerance analysis)
