For 2D problems, meshes with triangular or quadrilateral finite elements are common choices in numerical simulations involving partial differential equations. For complicated domains it can be challenging to generate high quality meshes with only quadrilateral elements. In this research, meshes with polygonal finite element shapes are generated and rational Wachspress-type functions are used for the finite element approximations. The finite element analysis is done using Matlab.

Medical imaging techniques such as Computer Tomography (CT) and MRI (Magnetic Resonance Imaging) are essential for 3D modeling. From a sequence of CT or MRI images, the 3D shape of a bone or aneurysm can be reconstructed. Loosening is a major reason for the failure of artificial joints.

Using computational models and simulation techniques, better performing implants and bone/implant connections can be designed.
