An interaction potential method for passive and active dynamics of hyperelastic materials
Francesco De Vita, Filippo Caruso Lombardi, Roberto Verzicco +1
Simulating active biological tissues, such as the myocardium, requires constitutive models that are both physically faithful and computationally efficient. The most common approach…
From Raw Segmentations to Simulation-Ready Cardiac Meshes: An Automated Framework for Anatomical Reconstruction and Virtual Cohort Generation
Francesco Fabbri, Martino Andrea Scarpolini, Paolo Ciancarella +4
Computational models of the human heart are widely used to study electromechanical and fluid-dynamical cardiac function and to support applications such as in silico clinical trial…
A fast and consistent sharp-interface immersed boundary method for moving bodies of arbitrary thickness
Giovanni Vagnoli, Martino Andrea Scarpolini, Roberto Verzicco +1
Immersed boundary methods (IBMs) are widely used to simulate flows around complex geometries and moving bodies, but they often involve a trade-off between precision and computation…
Hemodynamic effects of intra- and supra- deployment locations for a bioprosthetic aortic valve
Martino Andrea Scarpolini, Giovanni Vagnoli, Fabio Guglietta +2
Aortic valve replacement is a key surgical procedure for treating aortic valve pathologies, such as stenosis and regurgitation. The precise placement of the prosthetic valve relati…
A Quasi-Analytical Solution for "Carreau-Yasuda-like" Shear-thinning Fluids Flowing in Slightly Tapered Pipes
Gianluca Santesarti, Michele Marino, Francesco Viola +2
This paper presents a quasi-analytical framework for "Carreau-Yasuda-like" fluids with a viscosity characterized by two constant plateau at low and high shear rates connected by a…
An Insight into Parameter Identifiability Issues in the Carreau-Yasuda Model: a More Consistent Rheological Formulation for Shear-thinning non-Newtonian Inelastic Fluids
Gianluca Santesarti, Michele Marino, Francesco Viola +2
The Carreau-Yasuda rheological model is widely employed in both research and industrial applications to describe the shear-thinning behaviour of non-Newtonian inelastic fluids. How…
