Computational Modelling of Forces Acting on the Femur Bone: Stress Analysis in CFD Modules with Parallel Processing

The increasing incidence of bone fractures in the elderly or injured is considered to be a surgical
challenge for exerts. Following an experience of force applied to the femur bone surface triggered by
an external force at the level of bone articulation, increasing the risk of fracture following the
modification of biomechanics. Using the analysis by dynamic computational fluid (CFD), this study
aims to analyze the evolution of the proximal femur biomechanics in such cases and to extract
parameters such as strain and stress measurements which can predict the probability of fracture
within the femur bone and to simulate stress measurement in the bone and study their impact in the
case of external force exerted with successive values 10N, 50N and 100N.
A 3D femur bone models are constructed by configuring material and boundary conditions and
respecting patients' specific features, providing realistic and performant structural analysis. This study
describes a 3D construction process as well as the generation of the mesh based on a parallel
processing of eight processors.
