Crustal faults and sharp material transitions in the crust are usually represented as triangulated surfaces in structural geological models. The complex range of volumes separating such surfaces is typically three-dimensionally meshed in order to solve equations that describe crustal deformation with the finite-difference (FD) or finite-element (FEM) methods. We show here how the Boundary Eleme...

A new all-hexahedral meshing algorithm, referred to as “Geode”, is described. This algorithm is the combination of hex/tet plastering, dicing, and a new 26-hex transition element template.The algorithm is described in detail, and examples are given of problems meshed with this algorithm. keywords. Geode; hexahedral mesh generation; transition template.

finite and boundary element methods have been used by many authors to solve mathematicalphysics problems. however, the coupling of these two methods happens to be more efficient as it combinestheir merits. in this paper, the mathematical analysis of the coupling of finite and boundary element methodsfor the helmholtz equation is presented.

Microscopic digital volume correlation (DVC) and finite element precoalescence strain evaluations are compared for two nodular cast iron specimens. Displacement fields from \textit{in-situ} 3D synchrotron laminography images obtained by DVC. Subsequently the microstructure is explicitely meshed considering nodules as voids. Boundary conditions applied DVC measurement. Image segmentation-related...

Abstract We construct and analyze a domain decomposition method to solve class of singularly perturbed parabolic problems reaction-diffusion type having Robin boundary conditions. The considers three subdomains, which two are finely meshed, the other is coarsely meshed. partial differential equation associated with problem discretized using finite difference scheme on each subdomain, while cond...

An algorithm for the generation of hexahedral element meshes is demonstrated. The algorithm starts by creating a structured grid in the interior of an object. Then the boundary region is meshed by means of an isomorphism technique that uses basically 2D-operations. Examples are given that demonstrate the quality of the algorithm.

This paper presents the Finite Element Analysis (FEA) Multiphysics technique, applied to study strength of ice adhesion between surface polyurethane and ice. The theoretical this work is based on Euler-Bernoulli beam theory that used solve a four-point bending problem give correlation displacements with load longitudinal stresses. physical samples were prepared by freezing over tested experimen...

Advances in automotive lamp designs have resulted in a more compact, aerodynamic packaging and the use of less expensive plastic materials for the lens and housing. The smaller packaging and lower melting point of plastics have increased the need for a predictive tool for simulating the lamp temperature rise under operating conditions. The modeling of lamps requires sophisticated analysis tools...

objectives : this finite element method study aimed to compare the amount of stress on an isolated mandibular second premolar in two conventional reciprocal parallel interface designs of removable partial dentures (rpds) and the same rpd abutment tooth (not isolated). materials and methods: a kennedy class 1, modification 1 rpd framework was simulated on a 3d model of mandible with three differ...

in this study, an extended stress-based forming limit diagram (fld) for prediction of necking based on the marciniak and kucznski (m-k) model is represented and applied in tube hydroforming. the bulge forming of a straight tube is simulated by finite element method and verified with published experimental data. this adaptive simulation technique is based on the ability to detect the onset and g...
