Non linear transformation field to build moving meshes for patient specific blood flow simulations

Our study propose a method to build patient specific geometric data and boundary conditions for unsteady CFD runs with variable meshes valid over the cardiac cycle. We develop a specific MRI protocol in order to extract the full geometric data at several phases over the cardiac cycle. Hemodynamic boundary conditions were acquired by means of...

Fictitious Boundary and Moving Mesh Methods for the Numerical Simulation of Particulate Flow

This paper discusses numerical simulation techniques using a moving mesh approach together with the multigrid fictitious boundary method (FBM) for liquid-solid flow configurations. The flow is computed by an ALE formulation with a multigrid finite element solver (FEATFLOW), and the solid particles are allowed to move freely through the...
