Abstract: Abstract In this chapter, examples of advanced mesh morphing for biomechanical applications are presented demonstrating the benefits of meshless deformation for situations in which an underlying CAD geometry is not available. Virtual surgery using CFD simulation of the hemodynamics is faced showing how a morphing interaction can provide the insight in the estimation of the evolution of a pathology or to plan the insertion of a cannula in a virtual environment where patient shapes and medical devices shapes coexist and can interact. The use of mesh morphing for the remodelling is then demonstrated on a femur and a tibia bones. FEA method is adopted for the structural assessment and mesh morphing can be used as a tool to transform a baseline (library) geometry onto the patient one. The approach is useful not just as a simplified mesh generation tool (adapting is faster than remeshing), but rather because it allows to enable the direct comparison between models preserving the one-to-one nodes correspondence.
