Fluid-Structure Interaction in a Network of Blood Vessels

Model ID: 660


This model refers to a portion of the vascular system of a young child - the upper part of the aorta artery. The blood vessels are embedded in a biological tissue (the cardiac muscle) and, during the flow of blood, pressure is applied to the internal surfaces producing deformation of the vessel walls.

The complete analysis consists of two distinct but coupled procedures: a fluid-dynamics analysis with the calculation of the velocity field and pressure distribution in the blood (variable in time and in space) and the mechanical analysis with the deformation of the tissue and artery. The material is assumed to be nonlinear and a hyperelastic model is used.

This model was built using the following:
