ALE Mesh Updating using Mesh Optimisation
Accurate numerical simulation of problems in fluid mechanics requires using a method whereby the mesh can track free surfaces or fluid-solid or fluidfluid interfaces whilst coping with large distortions of the continuum. Such methods are referred to as Arbitrary Lagrangian Eulerian (ALE) methods and may be furthered studied in [1]. In order for the mesh to adapt to the deforming domain, a mesh ...
متن کاملA mesh generation procedure to simulate bimaterials
It is difficult to develop an algorithm which is able to generate the appropriate mesh around the interfaces in bimaterials. In this study, a corresponding algorithm is proposed for this class of unified structures made from different materials with arbitrary shapes. The non-uniform mesh is generated adaptively based on advancing front technique available in Abaqus software. Implementing severa...
متن کاملGeneration of Mesh Variants via Volumetrical Representation and Subsequent Mesh Optimisation
Having reliable finite element (FE) meshes is one of the basics of reliable FE simulations. As development times i.e. in the car industry are expected to decrease, engineers need to edit and optimise FE meshes without access to the underlying CAD geometry. If meshes are not only locally effected by the editing operation, simple mesh optimisations such as mesh relaxation or local remeshing are n...
متن کاملLocally optimal Delaunay-refinement and optimisation-based mesh generation
The field of mesh generation concerns the development of efficient algorithmic techniques to construct high-quality tessellations of complex geometrical objects. In this thesis, I investigate the problem of unstructured simplicial mesh generation for problems in R and R, in which meshes consist of collections of triangular and tetrahedral elements. I focus on the development of efficient algori...
متن کاملComparing Techniques for Tetrahedral Mesh Generation
The growing importance of subject-specific modeling and simulation in medical applications has increased the need for automatic techniques for creating high-quality meshes directly from medical data. We discuss the main aspects related to volumetric mesh generation from iso-surfaces. We take a practical approach, and the main focus of this paper is evaluating processing pipelines using widely a...
