62.2. Problem Description

A mouse-specific 3D geometry of the aortic lumen containing four side branches is considered:

3D Geometry of the Abdominal Aorta of a Mouse

The model represents an approximated geometry of the abdominal aorta of a mouse, based on the reference.[1] The geometry is considered at end-diastolic pressure (80 mm Hg). The purpose of the analysis is to solve for end-systolic pressure (120 mm Hg).

This figure shows the inner diameter of the model at various approximate locations:

The wall thickness is assumed to be 20 percent of the local radius, so it varies throughout the structure.
