Model order reduction of flow based on a modular geometrical approximation of blood vessels
Luca Pegolotti, Martin Pfaller, Alison Marsden +1
We are interested in a reduced order method for the efficient simulation of blood flow in arteries. The blood dynamics is modeled by means of the incompressible Navier-Stokes equat…
Automatic Mapping of Atrial Fiber Orientations for Patient-Specific Modeling of Cardiac Electromechanics using Image-Registration
Julia M. Hoermann, Martin R. Pfaller, Linda Avena +2
Knowledge of appropriate local fiber architecture is necessary to simulate patient-specific electromechanics in the human heart. However, it is not yet possible to reliably measure…
Parametric model order reduction and its application to inverse analysis of large nonlinear coupled cardiac problems
Martin R. Pfaller, Maria Cruz Varona, Johannes Lang +2
Predictive high-fidelity finite element simulations of human cardiac mechanics co\-mmon\-ly require a large number of structural degrees of freedom. Additionally, these models are…
The importance of the pericardium for cardiac biomechanics: From physiology to computational modeling
Martin R. Pfaller, Julia M. Hörmann, Martina Weigl +4
The human heart is enclosed in the pericardial cavity. The pericardium consists of a layered thin sac and is separated from the myocardium by a thin film of fluid. It provides a fi…
