How to Maintain Accurate Bone Geometries in Your FEA Meshes

About this webinar

The ideal numerical solution is one that is mesh-independent, yet improved meshing algorithms would lead to more reliable FEA results. Bone consists of complex geometry with a cortical and trabecular structure. In most of the FEA analysis, the trabecular bone is represented as a bulky volume inside the cortical bone. However, since the trabecular bone has a complex inhomogeneous structure, this simplification could have a significant effect on the accuracy of your simulation.

Dr. William Parr wanted to compare these two approaches using a simplified trabecular bone geometry and the actual trabecular bone structure in the ankle. Due to the bone’s complex geometry, it is difficult to maintain geometrical accuracy while converting the micro-CT scan into a high-quality FEA mesh. This led Dr. Parr to collaborate with Materialise’s R&D team to find easier ways of creating complex trabecular bone FEA meshes. During this webinar, he provided insight into his workflow and the results of his research.
