Image Processing, CAD Integration & FE Meshing
Simpleware modules ScanIP and +CAD were used to combine a segmented femur model taken from a CT scan with a CAD-designed implant. An FE mesh was then generated in the Simpleware +FE module and exported to ANSYS Workbench for micromotion simulation. The Simpleware API was used to automate the process of generating multiple implant positions.
FE meshes were generated for each implant position with approximately 10,000 nodes and 38,000 elements for the femur, and approximately 2,000 nodes and 6,000 elements for the implant, which was modelled as titanium. Standard material properties, node sets and loading conditions were also added, and refinements made at interfaces.
