Tutorials#
These tutorials are meant to guide the user through the basic steps of performing a computational fluid dynamic (CFD) simulation in a vascular body. The tutorials are divided into three main problems where we will first consider a model of the internal carotid artery (ICA) with an aneurysm, followed by a model of the left atrium. For the ICA, we will demonstrate different approaches for meshing and pre-processing of the model, followed by a CFD simulation using the Oasis software, before post-processing the results. For the left atrium model, we will investigate local refinement in a user-defined region, also followed by CFD simulation and post-processing of the results. In the third tutorial, we’ll explore a moving domain simulation for a simplified left atrium model, and examine blood residence time by simultaneously solving a scalar transport equation during the simulation.
We assume that you have VaMPy installed, meaning you have a working version
of morphMan and Oasis on your computer. For the
moving domain tutorial you will need to install OasisMove, a modified version
of Oasis for moving domain simulations. It is also beneficial, but not necessary, that you are familiar with
the ParaView visualization software, which we will frequently be using to visualize the
geometries and results.
