Presentation Title: FEM Analysis of Venous Valve Using Time-Dependent and Spatially-Varying Pressure Distributions Obtained from FSI Simulations

At the 39th International Conference on Modelling and Simulation organized by European Council for Modelling and Simulation, Emirhan Yiğit presented our study  on the FEM analysis of venous valves using the pressure distributions obtained in previous fluid-structure interaction (FSI) simulations.

In this study, first, we conducted a transient FSI simulation to obtain time-dependent and spatially varying loads on the valve leaflets, namely static pressure, dynamic pressure, and wall shear stresses. Then, these flow-induced loads were extracted at each time step and applied as transient and localized boundary conditions in a stand-alone finite element analysis. Unlike most existing studies that apply a single scalar pressure across the valve surface, our approach applies distinct node-by-node values, capturing a non-uniform pressure distribution. This additional structural model allowed us to isolate and investigate the valve’s mechanical response to different flow components in greater detail.
