Computational Modeling Approach to Profile Hemodynamical Behavior in a Healthy Aorta [PDF]
BioengineeringCardiovascular diseases (CVD) remain the leading cause of mortality among older adults. Early detection is critical as the prognosis for advanced-stage CVD is often poor.

On Linear Spaces of Polyhedral Meshes [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2015 Polyhedral meshes (PM) - meshes having planar faces - have enjoyed a rise in popularity in recent years due to their importance in architectural and industrial design. However, they are also notoriously difficult to generate and manipulate. Previous methods start with a smooth surface and then apply elaborate meshing schemes to create polyhedral meshes

Convex polyhedral meshing for robust solid modeling [PDF]
ACM Transactions on Graphics, 2021 We introduce a new technique to create a mesh of convex polyhedra representing the interior volume of a triangulated input surface. Our approach is particularly tolerant to defects in the input, which is allowed to self-intersect, to be non-manifold, disconnected, and to contain surface holes and gaps.

Polyhedral meshing in numerical analysis of conjugate heat transfer [PDF]
EPJ Web of Conferences, 2018 Computational methods have been widely applied in conjugate heat transfer analysis. The very first and crucial step in such research is the meshing process which consists in dividing the analysed geometry into numerous small control volumes (cells).

Coupling linear virtual element and non-linear finite volume methods for poroelasticity
Comptes Rendus. Mécanique, 2023 Solving poroelastic problems on a single grid is of paramount importance in the applications, especially in geosciences. However, these applications sometimes require to work with meshes made of distorted cells.

The Diamond Laplace for Polygonal and Polyhedral Meshes
Computer Graphics Forum, 2021 AbstractWe introduce a construction for discrete gradient operators that can be directly applied to arbitrary polygonal surface as well as polyhedral volume meshes. The main idea is to associate the gradient of functions defined at vertices of the mesh with diamonds: the region spanned by a dual edge together with its corresponding primal element — an ...

A computational method for sharp interface advection [PDF]
Royal Society Open Science, 2016 We devise a numerical method for passive advection of a surface, such as the interface between two incompressible fluids, across a computational mesh.
