While hexahedral mesh elements are preferred by a variety of simulation techniques, constructing quality all-hex meshes of general shapes remains a challenge. An attractive hex-meshing approach, often referred to as submapping, uses a low distortion mapping between the input model and a PolyCube (a solid formed from a union of cubes), to transfer a regular hex grid from the PolyCube to the inpu...

Simulation and predictions of material processes at multi-length scales require a detailed understanding of microstructures. While a meaningful study requires large data sets, the size of data sets has been limited due to the lack of automated image processing and mesh generation algorithms. We obtained as images a relatively large population of data from 19 samples of Aluminum foils by Electro...

SeisSol is a simulation software for seismic wave propagation and earthquake scenarios. It solves the fully elastic wave equations in heterogeneous media. Incorporating dynamic rupture simulation it performs complex multiphysics earthquake simulations. To account for complicated geometries SeisSol uses a fully unstructured tetrahedral mesh. Recent publications [1], [2] have shown that SeisSol i...

A boundary layer mesh is a mesh with dense element distribution in the normal direction along specific boundaries. PostBL is a utility to generate boundary layer elements on an existing mesh model. PostBL supports creation of hexahedral, prism, quad, and tri boundary layer elements. It is formulated as an algorithm in MeshKit, which is an open-source library for mesh generation functionalities....

A novel approach to unstructured quadrilateral mesh generation for planar domains is presented. Away from irregular vertices, the resulting meshes have the properties of nearly conformal grids. The technique is based on a theoretical relation between the present problem, and the inverse Poisson (IP) problem with point sources. An IP algorithm is described, which constructs a point-source distri...

One of the major issues of mesh generation today is access to CAD geometry in an accurate and efficient manner. This paper will provide an overview the process of accessing CAD geometry for mesh generation and will review several of the issues associated with accessing CAD geometry for mesh generation. This paper will also evaluate alternative techniques for accessing CAD geometry and review ho...

Finite Element mesh generation remains an important issue for patient specific biomechanical modeling. While some techniques make automatic mesh generation possible, in most cases, manual mesh generation is preferred for better control over the sub-domain representation, element type, layout and refinement that it provides. Yet, this option is time consuming and not suited for intraoperative si...

objectives: indicators of oral health-related quality of life (ohrqol) in children are widely adopted to evaluate the effects of oral problems. recently, the scale of oral health outcomes for 5-year-old children (soho-5) was developed based on the children’s self-reports. this study aimed to evaluate the validity and reliability of the persian version of the questionnaire in a sample of iranian...

In this research work, cut mesh design optimization for the induction bonding process using genetic algorithms (GAs) is investigated to solve the problem of nonuniform heating, which leads to nonuniform temperature fields and temperature gradients exceeding the process window required for bonding. Cut patterns in the metal mesh can redirect the magnetically induced electric currents generated t...
