This research aims at devising a framework between a CFD model and a derived biomechanical model that effectively makes AAA (abdominal aortic aneurysms) therapeutics more accurate. The input data required is patient abdominal CT-imaging scans using CAD software's and features we can extract out of the vessel geometry in which, after meshing, we can simulate the blood flow using CFD in Ansys Fluent. This blood flow CFD simulation helps us identify the high-pressure or stressed regions of the vessel wall. Using the biomechanical factors affecting aneurysmal expansion, a model to quantify expansion per unit time was derived. This model took into consideration factors like compliance, elastic modulus, and other mechanical properties. Using the geometrical parameters that can be acquired from VMTK processing on the CAD vessel geometry and variable parameters like pressure and velocity from the CFD simulation, the date of rupture can be approximated, thus precisifying aneurysmal therapeutics.
