The purpose of this talk is to present a pipeline for hexahedral mesh generation and fast hemodynamic indeces computation for patient-specific coronary arteries. Regarding the mesh generator, the main novelty is represented by the Hermite-based modeling non-planar bifurcations, the possibility of easily control the mesh connectivity and a fast and efficient mesh generation thanks to the complete spline approach. The mesh generator is applied to the FAME 2 dataset, and the meshes are evaluated based on commonly employed indices demonstrating the performance of the proposed method. Finally, we present numerical fluid dynamics results for a selected set of geometries and demonstrate how, through controlled connectivity, they can enhance a machine learning model to efficiently compute the FFR index.
