Tetrahedral mesh segmentation based on quality criteria
(Ieee, 2016-01-01)
Simulations based on the Finite Element Method are widely applied in different contexts. The convergence and reliability of results depends directly on the quality of the tetrahedrons that compose FEM meshes. In this ...

Multiscale tetrahedral meshes for FEM simulations of esophageal injury
(2015-01-01)
The radiofrequency cardiac ablation is a minimal invasive surgical procedure used for treating tachycardia, atrial fibrillation and atrial flutter. A possible complication is esophageal injury: The union of tissues from ...
Vocal folds vibrations with a three-dimensional deformable model
(2006-12-01)
In this work a computational method is presented to simulate the movements of vocal folds in three dimensions. The proposed model consists of a mesh free structure where each vertex is connected its neighbor through a group ...
Multiscale modeling of steel fiber reinforced concrete based on the use of coupling finite elements and mesh fragmentation technique
(2018-01-01)
A multiscale model is proposed based on the use of coupling finite elements recently developed by the authors. This feature allows the use of the same strategy to deal with two problems of non-matching meshes addressed in ...

Delaunay Tetrahedralization of the Heart Based on Integration of Open Source Codes
(Iop Publishing Ltd, 2014-01-01)
The Finite Element Method (FEM) is a way of numerical solution applied in different areas, as simulations used in studies to improve cardiac ablation procedures. For this purpose, the meshes should have the same size and ...
Modeling drying cracks in soils using a mesh fragmentation method
(2015-01-01)
Desiccation cracks in soils act as a preferential path for water flow and pollutant transport. Drying cracks also affect soil strength and may lead to stability in embankments and slopes. The presence of desiccation cracks ...
