After developing our own training course from the ground up, we put together a new online training class, FEA Modeling with Simcenter and NX Nastran. The class uses a blend of theory & practice, showing the experienced student how to build complex and accurate FEA models of structures and systems.

This class is available for purchase through Amazon and comes with:
• Access to nearly 6 hours of narrated step-by-step video tutorials
• 208 page spiral-bound class notes
• Workshop projects and model files with starting CAD geometry and finished model comparison files

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.
