svMultiPhysics: a finite element-based solver for cardiovascular simulations
David Codoni, Sujal Dave, David W. Parker +10
Heart disease remains the leading cause of death in the United States, motivating extensive efforts to improve its diagnosis, treatment, and prevention. Over the past decade, compu…
Coupling models of resistive valves to muscle mechanics in cardiac fluid-structure interaction simulations
Michele Bucelli, Luca Dede'
To accurately simulate all phases of the cardiac cycle, computational models of hemodynamics in heart chambers need to include a sufficiently faithful model of cardiac valves. This…
Influence of cellular mechano-calcium feedback in numerical models of cardiac electromechanics
Irena Radišić, Francesco Regazzoni, Michele Bucelli +3
Multiphysics and multiscale mathematical models enable the non-invasive study of cardiac function. These models often rely on simplifying assumptions that neglect certain biophysic…
Coupled Eikonal problems to model cardiac reentries in Purkinje network and myocardium
Samuele Brunati, Michele Bucelli, Roberto Piersanti +2
We propose a novel partitioned scheme based on Eikonal equations to model the coupled propagation of the electrical signal in the His-Purkinje system and in the myocardium for card…
The lifex library version 2.0
Michele Bucelli
This article presents updates to lifex [Africa, SoftwareX (2022)], a C++ library for high-performance finite element simulations of multiphysics, multiscale and multidomain problem…
Robust radial basis function interpolation based on geodesic distance for the numerical coupling of multiphysics problems
Michele Bucelli, Francesco Regazzoni, Luca Dede' +1
Multiphysics simulations frequently require transferring solution fields between subproblems with non-matching spatial discretizations, typically using interpolation techniques. St…
lifex-ep: a robust and efficient software for cardiac electrophysiology simulations
Pasquale C. Africa, Roberto Piersanti, Francesco Regazzoni +6
Simulating the cardiac function requires the numerical solution of multi-physics and multi-scale mathematical models. This underscores the need for streamlined, accurate, and high-…
Preserving the positivity of the deformation gradient determinant in intergrid interpolation by combining RBFs and SVD: application to cardiac electromechanics
Michele Bucelli, Francesco Regazzoni, Luca Dede' +1
The accurate robust and efficient transfer of the deformation gradient tensor between meshes of different resolution is crucial in cardiac electromechanics simulations. We present…
