Abstract:
The objective of the project is to simulate the blood circulation in the liver. The
geometry of the liver is obtained from medical images. The liver is then modeled as a porous medium that verifies Darcy’s law. We use the Abaqus software to perform the simulation with the finite element method, the software calculates the pressure in the pores and blood flow velocity. We check the Darcy equation in the porous medium using two simple examples: infiltration through a dam and then a simplified hepatic lobule. These two models allow us to compare the numerical results and analytical results, and to validate Darcy’s law implemented in Abaqus. We have also created a hexagonal lobule, which aims to compare with the article by J. H. Siggers et al. We then investigated a complete liver model, using the geometry available on the IRCAD website. These are surface models that do not take volume into account. So, we used the CATIA software to reconstruct the geometry of the liver and its veins. Finally, Abaqus software allows us to simulate the flow of blood in the liver and its veins.
