FESOM-C v.2: coastal dynamics on hybrid unstructured meshes [PDF]
We describe FESOM-C, the coastal branch of the Finite-volumE Sea ice – Ocean Model (FESOM2), which shares with FESOM2 many numerical aspects, in particular its finite-volume cell-vertex discretization.

Mesh-Free MLS-Based Error-Recovery Technique for Finite Element Incompressible Elastic Computations
The finite element error and adaptive analysis are implemented in finite element procedures to increase the reliability of numerical analyses. In this paper, the mesh-free error-recovery technique based on moving least squares (MLS) interpolation is ...

New Weights for Estimating Normal Surface in the Triangular Mesh [PDF]
The normal vector at a node on the discrete surface is not unique, when a surface discretized by triangular elements. A widely used technique to estimate the normal vector at a giving node is a weighted average of the exact normal of the surrounding ...

Guaranteed-Quality Triangular Meshes [PDF]
There are a number of applications for which it is desirable to divide a given region in the plane into nicely shaped triangles. One important such application is the finite element method, a method widely used to obtain approximate solutions to a wide variety of engineering problems.

We define and examine flip operations for quadrilateral and hexahedral meshes, similar to the flipping transformations previously used in triangular and tetrahedral mesh generation.Comment: 20 pages, 24 figures.

This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

A detail-preserving method for medial mesh computation in triangular meshes
The medial axis transform (MAT) of an object is the set of all points inside the object that have more than one closest point on the object’s boundary. Representing sharp edges and corners of triangular meshes using MAT poses a complex challenge.

Boolean operations between two colliding shells: a robust, exact, and simple method
Boolean operations are classic procedures in computer-aided design, and allow the creation of complex objects by combining simple objects. Although Boolean operations are trivial in implicit surface representations, they are problematic in polygonal ...

Hybrid mesh for magnetotelluric forward modeling based on the finite element method
Unstructured tetrahedral grids have been applied in magnetotelluric (MT) forward modeling using the finite element (FE) method because of their adaptability to complex anomalies.

Geodesic paths on triangular meshes [PDF]
We present a new algorithm to compute a geodesic path over a triangulated surface. Based on Sethian's (1996) fast marching method and Polthier's (1998) straightest geodesics theory, we are able to generate an iterative process to obtain a good discrete geodesic approximation. It can handle convex and nonconvex surfaces as well.
