Finite Element Analysis (FEA)

Introduction

Finite Element Analysis (FEA) is a technique allowing virtual prediction of the structural mechanics and performance of a design.


The examples presented below represent a non-exhaustive list of simulations I've created for public-facing content or publications. For additional information on commercial projects I've worked on, please contact me directly.

Large Assembly Analysis

Managing complexity in multi-component systems.

  • Simplification of models featuring 1,000+ components
  • Virtual modeling of bolted joints, welds, and other fasteners
  • Meshing techniques balancing solve time and accuracy

Background & Methodology

Over the course of 10+ years, I've utilized finite element analysis to assess the performance of parts, products, and assemblies from hundreds of customers and clients- guiding them through the entire process from forming an analysis plan, preparing CAD models and other geometry, solving, reporting, and interpreting results.

I work closely with stakeholders to ensure that every simulation provides actionable data focused on their needs by verifying that we are solving the correct problem in a level of fidelity appropriate for the current phase of their product development cycle.
