An in-silico benchmark for the tricuspid heart valve – Geometry, finite element mesh, Abaqus simulation, and result data set

Abstract This article provides the Abaqus input files and user subroutine for performing finite element simulations of the tricuspid heart valve with an idealized geometry. Additional post-processing steps to obtain a ParaView visualization file ( *.vtk ) of the deformed geometry are provided to allow the readers to use the included ParaView state file ( *.pvsm ) for customizable visualization and evaluation of the simulation results. We expect this first-of-its-kind in-silico benchmark dataset will facilitate user-friendly simulations considering material nonlinearity, leaflet-to-leaflet contact, and large deformations. Additionally, the information included herein can be used to rapidly evaluate novel in-silico approaches for simulating cardiac valve function. The benchmark can be expanded to consider more complex features of the tricuspid valve function, such as the dynamic annulus motion or the time-varying transvalvular pressure. Interested readers are referred to the companion article [1] for an example application of this in-silico tool for isogeometric analysis of tricuspid valves.
