The application of mechanical principles for solving biological problems has been dynamically expanding and CAE simulations have found effective application for biomechanics studies.
In the new article published in the Italian journal “Analisi e Calcolo” n° 76 Sep. 2016 two important applications of the mesh morphing in biomechanics simulation, both in cases of hemodynamic are presented.
In the first case we focused our attention on the study of a subject-specific carotid bifurcation being this anatomical site of major interest in hemodynamics. We presented a new workflow based on three fully validated software used to elegantly fulfill the requirements related to hemodynamics: the Vascular Modeling Toolkit (VMTK) for the pre-processing step; the RBF Morph mesh morphing tool to impose changes to the vascular anatomy; Ansys Fluent as Navier-Stokes solver and CFD modeler.
In the second example, we implemented a computational fluid dynamics (CFD) model to numerically assess the fluid dynamics generated by the arterial cannula. Mesh morphing techniques based on radial basis functions (RBF) are used to explore clinical use parameters that influence surgery performances.
