Addressing Integration Error for Polygonal Finite Elements Through Polynomial Projections: A Patch Test Connection [PDF]
Polygonal finite elements generally do not pass the patch test as a result of quadrature error in the evaluation of weak form integrals. In this work, we examine the consequences of lack of polynomial consistency and show that it can lead to a ...

Compressing the property mapping of polygon meshes [PDF]
Summary: Many polygon meshes have properties such as shading normals, colors, texture coordinates, or material attributes that are associated with the vertices, faces, or corners of the mesh. While current research in mesh compression has focused on connectivity and geometry coding, the compression of properties has received less attention.

On the Virtual Element Method for Topology Optimization on polygonal meshes: a numerical study [PDF]
It is well known that the solution of topology optimization problems may be affected both by the geometric properties of the computational mesh, which can steer the minimization process towards local (and non-physical) minima, and by the accuracy of the ...

Anisotropic mesh quality measures and adaptation for polygonal meshes [PDF]
Anisotropic mesh quality measures and anisotropic mesh adaptation are studied for polygonal meshes. Three sets of alignment and equidistribution measures are developed, one based on least squares fitting, one based on generalized barycentric mapping, and the other based on singular value decomposition of edge matrices.

Tsallis Entropy for Geometry Simplification
This paper presents a study and a comparison of the use of different information-theoretic measures for polygonal mesh simplification. Generalized measures from Information Theory such as Havrda–Charvát–Tsallis entropy and mutual information have been ...

Accurate and efficient surface reconstruction from volume fraction data on general meshes [PDF]
Simulations involving free surfaces and fluid interfaces are important in many areas of engineering. There is, however, still a need for improved simulation methods. Recently, a new efficient geometric VOF method called isoAdvector for general polyhedral

Construction of Supplemental Functions for Direct Serendipity and Mixed Finite Elements on Polygons
New families of direct serendipity and direct mixed finite elements on general planar, strictly convex polygons were recently defined by the authors. The finite elements of index r are H1 and H(div) conforming, respectively, and approximate optimally to ...

Virtual Elements for the Navier-Stokes problem on polygonal meshes [PDF]
A family of Virtual Element Methods for the 2D Navier-Stokes equations is proposed and analysed. The schemes provide a discrete velocity field which is point-wise divergence-free.
