Mesh Independence Study for CFD Models of Intracranial Aneurysms
Mentors: Ashley Taepakdee, MD and Chung-Hao Lee, PhD
Intracranial aneurysms are often asymptomatic, but can be fatal when ruptured -leading
to massive internal bleeding. Studying blood flow within an aneurysm is one way to predict aneurysm rupture potential. Computer models enable the study of aneurysms while saving money, time, and resources in comparison to in vitro and in vivo studies. Computer models use meshes to break up three-dimensional geometries into smaller elements for analysis. It is important to find the most accurate mesh, while also considering computational cost and time.
For this study, three aneurysm geometries were created on Solidworks and inputted into Comsol to obtain the velocity within the anewysms. The meshes for each geometry were changed and the average percent difference from the most accurate mesh was calculated to figure out the ideal mesh for each geometry. Using these accurate meshes helps progress research on intracranial aneurysms by providing additional information.
