Abstract:
Three-dimensional finite element method (FEM) is widely used as an effective numerical simulation technique to solve the complex engineering problem. In the FEM simulation technique at first it needs to discrete the problem. However, the almost all of the engineering problem have very complicated structure and shape, so that the mesh generation also have much difficulty. Furthermore, the correct generation of mesh is one of the most significant issues that directly affect to the accuracy of the FEM simulation. Though in extensive commercial software have an excellent automatic mesh generating

Abstract:
Hexahedral elements provide greater accuracy and efficiency over tetrahedral elements for finite element analysis of solids and for this reason the all-hexahedral element auto meshing has a growing demand. The whisker-weaving based plastering algorithm developed by the authors can generate hexahedral mesh (HM) automatically. In this method the prerequisite for generating HM is quadrilateral surface mesh (SM). From the given SM, combinatorial dual cycles or whisker sheet loops for whisker weaving algorithm are generated to produce HM. Generation of good quality HM does not depend only on the qu

Abstract:
MG (multigrid) method is one of the most promising solvers for large scale problems. Hexahedral mesh generation and its adaptation are not enough to use for practical applications, because its mesh generation is very difficult and still labor intensive work by hand. We have developed hexahedral local refinement technique controlled by posterior error estimation. We have proposed a MG technique for unstructured hexahedral meshes with local mesh refinement. In this paper, the proposed technique is evaluated to check its performance and severe analyses of bending cantilevers. Performance of MG fo

Abstract:
Abstract Volumetric decomposition is essential for all-hexahedral mesh generation. Because fully automatic decomposition methods that can generate high-quality hexahedral meshes for arbitrary volumes have yet to be realized, manual decomposition is still required frequently. Manual decomposition is a laborious process and requires a high level of user expertise. Therefore, a user-guided semi-automatic tool to reduce the human effort and lower the requirement of expertise is necessary. To date, only a few of these approaches have been proposed, and a lack of user evaluation makes it difficult t

For this purpose, a semi-automatic all-hexahedral mesh generation algorithm is developed and implemented.

Abstract:
Abstract A method has been developed to generate regular hexahedral meshes automatically from arbitrary solid models by volume decomposition. This method first decomposes a solid model having a complex shape into volumes having simple shapes. Then, shape-specific meshing methods like mapping are applied to generate regular hexahedral meshes from these volumes. Finally, all regular hexahedral meshes of these volumes are combined into a regular hexahedral mesh of the original solid model. Thus the method generates regular hexahedral meshes automatically in a way similar to the way a human does i

Abstract:
Hexahedral mesh generation is difficult and time-consuming. To avoid the complicated hexahedral mesh regeneration after each variational design, hexahedral mesh editing can be used. In this paper, an accurate hexahedral mesh cutting approach using geometric model is proposed, and the part of the geometric model inside the mesh model can be complex and arbitrary. In the approach, all the newly added geometric entities resulted from mesh cutting are first generated by performing the subtraction operation between the mesh model and the geometric model. Then, for each newly added geometric element

Automated tetrahedral meshing from manifold tessellated optical scan data is investigated to determine its viability as an approach for finite element analysis.

The broad objective of our software, IA-FEMesh is to aid patient-specific finite element (FE) model development. Patient-specific models hold the potential to enable surgeons to plan care using objective analysis-based tools. Thus, they can better evaluate alternate surgical protocols and treatments, thereby contributing to improved surgical outcome. Our previous efforts were focused on projection techniques specific to the geometry under consideration [1]. The current meshing technique is the generalization of projection techniques that builds upon a multi-block approach, with considerable at
