FUSE: A Partitioned Field-Exchange Framework for Coupling Physics Simulations in FEBio
Steve A. Maas, Farhan Muhib, Jeffrey A. Weiss
Computational biomechanics increasingly requires models that combine mechanics, transport, chemistry, and biological regulation across different spatial and temporal scales. The FE…
An open-source computational framework for immersed fluid-structure interaction modeling using FEBio and MFEM
Ryan T. Black, Steve A. Maas, Wensi Wu +4
Fluid-structure interaction (FSI) simulation of biological systems presents significant computational challenges, particularly for applications involving large structural deformati…
Effect of Right Ventricular Outflow Tract Material Properties on Simulated Transcatheter Pulmonary Placement
Jalaj Maheshwari, Wensi Wu, Christopher N. Zelonis +9
Finite element (FE) simulations emulating transcatheter pulmonary valve (TPV) system deployment in patient-specific right ventricular outflow tracts (RVOT) assume material properti…
Integrated Open-Source Framework for Simulation of Transcatheter Pulmonary Valves in Native Right Ventricular Outflow Tracts
Christopher N. Zelonis, Jalaj Maheshwari, Wensi Wu +14
Background - Pulmonary insufficiency is a consequence of transannular patch repair in Tetralogy of Fallot (ToF), leading to late morbidity and mortality. Transcatheter native outfl…
Simulation of Transcatheter Therapies for Atrioventricular Valve Regurgitation in an Open-Source Finite Element Simulation Framework
Seda Aslan, Nicolas R. Mangine, Devin W. Laurence +8
Purpose: Transcatheter edge-to-edge repair (TEER) and annuloplasty devices are increasingly used to treat mitral valve regurgitation, yet their mechanical effects and interactions…
Effect of Parametric Variation of Chordae Tendineae Structure on Simulated Atrioventricular Valve Closure
Nicolas R. Mangine, Devin W. Laurence, Patricia M. Sabin +9
Many approaches have been used to model chordae tendineae geometries in finite element simulations of atrioventricular heart valves. Unfortunately, current "functional" chordae ten…
