Nathan Anderson

Instructor Nathan Anderson

With 8 years of experience, Nathan Anderson, PE, started his engineering career as a design engineer for a large equipment manufacturer. He quickly gravitated toward simulation and analysis to solve his engineering challenges. He also works in programming, using code to improve productivity whenever possible. With either the FEMAP API or the .net framework he can help  develop custom automation of FEMAP, NX CAE, or standalone applications.
