FEBio with PreView, PostView plugins is a nonlinear finite element solver which offers a chance to study it and to predict the future regions of rupture to some extent via Computational Fluid Dynamics (CFD) features. 3-matic provides an easy interface to do the dimensional analysis using imported aneurysm morphology.
#FEBIO POSTVIEW SOFTWARE#
MIMICS software is used for modeling the aneurysms using three types of Axial, Coronal, and Saggital views. MATLAB is used to segment the Aorta irrespective of intensity/contrast inhomogeneities using Solidity feature. The ultimate goal is to develop a 3D printed aneurysm replica for further evaluation and analysis using Ultimaker Cura Slicer Software. The objective of this work is to provide an extensive study on AAA segmentation, modeling and analysis with individual frameworks in sequence using tools like MATrix LABoratory (MATLAB), Materialise’s Interactive Medical Image Control System (MIMICS), 3-matic and Finite Element Biomechanics (FEBio). Morphological study provides approximate dimensions and risk of rupture. Hence it’s better to analyze, segment and model them to aid physicians/surgeons in various aspects of nonsurgical and surgical treatments. They are usually saccular, fusiform according to their shape statistics. Abnormal swelling at the aorta causes Abdominal Aortic Aneurysm (AAA).

A Novel Framework on Abdominal Aortic Aneurysm Analysis Based on Biomedical Simulation Tools The model depicted above still fails due to penetrating tets, which we will address differently. Thus far, we have had success in both approaches. Remesh (using tetgen) the original mesh and restart simulation.Remesh (using tetgen) the failed model and continue simulating from the failed time-step.To solve this issue, we have approached the problem in two ways: The resultant mesh features about 1.1M tets and a minimum dihedral angle = 4.80, which is now the parameter we are tracking the most.Īs is, using FEBio, we probably get about 20% of the simulation done before one or multiple tets invert (i.e.
I would also note that we are now smoothing the compartments heavily prior to meshing, so our latest -blend_sigma parameters are small. The most effective parameters were -scale 1.00 -multiplier 2.00 -grading 5.00 -blend_sigma 1.75.
The initial mesh was generated using the Segment Mesher module and Cleaver2. If I did not mention this earlier, we are using FEBio for the FEA and PostView for visualization.
