Enabling Massive Biomechanical Sims
My custom-built tools (written in C++) have enabled these world leading bio-mechanics researchers to simulate at higher resolution than ever before. This research is improving simulation accuracy. These simulations are used to develop better surgical implants and surgical devices.

Introduction:
Understanding how the trabecular and cortical compartments contribute to the load-bearing capacity of the human proximal femur has important implications to both clinical practice and basic-science. Advances in computing power and computed-tomography (CT) scanners over the last two decades now makes it possible to run large-scale micro-structural finite element (FE) analysis of the femur, providing in-depth information on the trabecular and cortical bone mechanics.
However, current microstructural femur models require large supercomputing power, ad-hoc software and the common point-load simplification of the hip contact force that lead to numerical artefacts in the femoral head region. We present a novel software pipeline for generating micro-structural FE models of the human femur, determine the hip pressure distribution on the femoral head, solve the elastic problem and post-process the large result file.
