Journal ArticleDOI
Topological sensitivity analysis
TL;DR: In this article, the authors proposed an alternative way to compute the topological derivative based on the shape sensitivity analysis concepts, which leads to a more simple and constructive formulation than the ones found in the literature.
Journal ArticleDOI
On micro‐to‐macro transitions for multi‐scale analysis of non‐linear heterogeneous materials: unified variational basis and finite element implementation
Journal ArticleDOI
An Anatomically Detailed Arterial Network Model for One-Dimensional Computational Hemodynamics
Pablo J. Blanco,Sansuke M. Watanabe,Marco Aurelio R. F. Passos,Pedro A. Lemos,Raúl A. Feijóo +4 more
TL;DR: The present model features excellent descriptive and predictive capabilities in both patient-generic and patient-specific cases, presenting a new step toward integrating an unprecedented anatomical description, morphometric, and simulations data to help in understanding complex arterial blood flow phenomena and related cardiovascular diseases.
Journal ArticleDOI
Multidimensional modelling for the carotid artery blood flow
TL;DR: In this paper, a multidimensional 3D-1D FEM model of the whole arterial tree is implemented, consisting of a 3D compliant model of carotid bifurcation coupled with a 1D model for the remaining part of the tree.
Journal ArticleDOI
A unified variational approach for coupling 3D-1D models and its blood flow applications
TL;DR: An extended variational formulation is proposed in order to handle the problem of the flow of an incompressible fluid in compliant vessels with discontinuous fields and makes possible to tackle in a consistent variational manner problems like the coupling between models of different dimensionality.
