SUMMARY In this paper, a robust and semi‐automatic modelling pipeline for blood flow through subject‐specific arterial geometries is presented. The framework developed consists of image segmentation, domain discretization (meshing) and fluid dynamics. All the three subtopics of the pipeline are expl...
