In practice, the input is typically a set of unprocessed polygonal surfaces coming either from a template geometry or from medical images. These surfaces need ad\u2010hoc processing to be suitable for a volumetric mesh generation. In this work we propose a set of new algorithms and tools aiming to facilitate the mesh generation process. In particular, we focus on different aspects of a cardiac mesh generation pipeline: (1) specific polygonal surface processing for cardiac geometries, like connection of different heart chambers or segmentation outputs; (2) generation of accurate boundary tags; (3) definition of mesh\u2010size functions dependent on relevant geometric quantities; (4) processing and connecting together several volumetric meshes. The new algorithms\u2014implemented in the open\u2010source software vmtk\u2014can be combined with each other allowing the creation of personalized pipelines, that can be optimized for each cardiac geometry or for each aspect of the cardiac function to be modeled. Thanks to these features, the proposed tools can significantly speed\u2010up the mesh generation process for a large range of cardiac applications, from single\u2010chamber single\u2010physics simulations to multi\u2010chambers multi\u2010physics simulations. We detail all the proposed algorithms motivating them in the cardiac context and we highlight their flexibility by showing different examples of cardiac mesh generation pipelines.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Marco Fedele, Alfio QuarteroniNumerical methods in Biomedical Engineering Open Access: https:\/\/onlinelibrary.wiley.com\/doi\/full\/10.1002\/cnm.3435DOI: https:\/\/doi.org\/10.1002\/ AbstractIn order to simulate the cardiac function for a patient\u2010specific geometry, the generation of the computational mesh is crucially important.
