“…That type of boundary triangles contains two boundary edges. If the formerly mentioned (Gopalsamy et al 2005) methodology is applied to those triangles, the boundary edges will be placed in a straight line on the 2D square domain so they will not form a triangle anymore. As a result, the exact shape cannot be fully reproduced and piece of information is lost.…”

This study presents the generation of a multi-block structured grid on a real abdominal aortic aneurysm (AAA) acquired from Digital Imaging and Communication in Medicine (DICOM) data. With the use of a computed tomography exam (or medical images in standard DICOM format), the shape of a human organ is extracted and a structured computational grid is created. The structured grid generation is done by utilising Floater's and Gopalsamy et al.'s algorithm. The proposed methodology is applied to the AAA case, but it may also be applied to other human organs, enabling the scientist to develop an advanced patient-specific model. More importantly, the proposed methodology provides a precise reconstruction of the human organs, which is required in an AAA, where small variations in the geometry may alter the flow field, the stresses exerted on the walls and finally the rupture risk of the aneurysm.
