We present an anisotropic adaptive discretization method and demonstrate how computational
efficiency can be increased when applying it to the simulation of cardiovascular flow. We …

In this work, we describe the CRIMSON (CardiovasculaR Integrated Modelling and
SimulatiON) software environment. CRIMSON provides a powerful, customizable and user-friendly …

… approximation errors associated with it (for details see Sahni et al. 2006). In this study, we
have employed boundary-layer mesh adaptivity (Sahni et al. 2008) that maintains favourable …

A procedure for anisotropic mesh adaptation accounting for mixed element types and
boundary layer meshes is presented. The method allows to automatically construct meshes on …

In this study, we present an adaptive anisotropic finite element method (FEM) and
demonstrate how computational efficiency can be increased when applying the method to the …

In this paper, we extend the Park and Jensen wake model to include the effects of yaw angle
rotation and wake deflection of wind turbines. We first perform a numerical study to find the …

elements up to 32,768 cores (6 core-doublings) and O(10 9 ) elements up to 163,840 cores. …

… The work developed by Sahni [37] is used to adapt the mesh resulting in improved resolution.
In general, a mesh with high enough resolution to provide mesh-independence is used to …
