Abstract

In this paper novel finite element algorithms for robustly solving flow equations of asystemic circulation are presented and compared. A novel, Locally Conservative Galerkin (LCG)method is developed by adopting semi- and fully- implicit time discretisations to address the behaviourof blood flow in t...
