WKBM: A hepatic artery blood flow analysis solver based on 3-Element WindKessel model

Understanding the blood flow inside the hepatic artery has an auxiliary function for interventional therapy. Doctors can formulate corresponding plans for interventional therapy according to the results of hemodynamic analysis. The 3-Element Windkessel model is a model widely used to simulate blood flow in vascular systems. The purpose of this study is to use the open source computational fluid dynamics (CFD) software OpenFOAM for blood flow analysis, and to design a 3-Element Winkessel model numerical solver WK_BathforthMoulton to simulate the blood flow of the patient's hepatic artery. The 3-Element Windkessel model equation is implemented in the custom solver, and Adams-Bathforth and Adams-Moulton methods are used for numerical calculation.
