Manual vs. automatic meshing for FEA bone strain prediction: validation against experimental data

2012
Student Projects

Résumé

Despite recent progress, Finite Element Analysis (FEA) of bone based on microCT imaging involves many manual steps and assumptions, being time consuming and error prone.As a consequence, these different modeling strategies may not necessary lead to the same results. Therefore, the objective of this project is to compare and highlight the strength and weaknesses of two FEA procedures. The 1st procedure is mostly manual and based on commercial software for segmentation, surface extraction and volume meshing. The 2nd procedure is semi-automatic, developed at LMAF for subject-specific FEA model generation. During this project, each step of the two procedures will be compared to highlight the potential differences between the methods. The 1st procedure will be achieved and supervised at the LBO and the 2nd one at the LMAF. Finally, the two FEA will be validated with respect to experimental data available at LMAF. This work will improve FEA of bone based on microCT.

Types of mesh

A mesh is a representation of a larger geometric domain by smaller discrete cells. Meshes are commonly used to compute solutions of partial differential equations and render computer graphics, and to analyze geographical and cartographic data. A mesh partitions space into elements (or cells or zones) over which the equations can be solved, which then approximates the solution over the larger domain. Element boundaries may be constrained to lie on internal or external boundaries within a model.

Commercial software

Commercial software, or seldom payware, is a computer software that is produced for sale or that serves commercial purposes. Commercial software can be proprietary software or free and open-source software. While software creation by programming is a time and labor-intensive process, comparable to the creation of physical goods, the reproduction, duplication and sharing of software as digital goods is in comparison disproportionately easy. No special machines or expensive additional resources are required, unlike almost all physical goods and products.

Mesh generation

Mesh generation is the practice of creating a mesh, a subdivision of a continuous geometric space into discrete geometric and topological cells. Often these cells form a simplicial complex. Usually the cells partition the geometric input domain. Mesh cells are used as discrete local approximations of the larger domain. Meshes are created by computer algorithms, often with human guidance through a GUI , depending on the complexity of the domain and the type of mesh desired.
