Finite Element Mesh Generation of Human Body Segment in 2-D and 3-D Using B-splineMethod

AbstractIn studying subject specific biomechanical behavior of bio-object, finite element method offers number of advantages. Mesh generation and assignment of material property to each element-node is a fundamental and key issue in generation of accurate finite element model of any biological structure. Researchers offered number of methods of mesh generation to subject specific bio-object. In this work, we present B-spline based modeling and mesh generation methodology for bio-object like human body is presented. The distinct advantage of this method is that modeling and meshing is done in a single step along with true representation of material. For demonstration, mesh models of child femur, adult femur and a head from volumetric CT scan data are presented in 2D and 3D. A minimal scaled Jacobian criterion is used to evaluate the quality of quadrilateral and hexahedral elements. The results show that all quadrilateral and hexahedral element meshes are well shaped and able to capture both geometric and m...
