Evolutionary Generation of Primitive-Based Mesh Abstractions

A Semantics-based Approach to Optimizing Unstructured Mesh Abstractions

ions obfuscate; they should instead illuminate. The use of high-level abstractions, such as matrices and differential operators, is a key to achieving high-productivity scientific computing [44]. Abstractions are frequently implemented in domain-specific libraries as user-defined types and the procedures acting on them. Such abstractions are a closer match to the concepts and notations employed...

Appraisal of the evolutionary-based methodologies in generation of artificial earthquake time histories

Through the last three decades different seismological and engineering approaches for the generation of artificial earthquakes have been proposed. Selection of an appropriate method for the generation of applicable artificial earthquake accelerograms (AEAs) has been a challenging subject in the time history analysis of the structures in the case of the absence of sufficient recorded accelerogra...

Sheet-Based Hexahedral Mesh Generation

Historically, hexahedral finite element mesh generation has required significant geometric decomposition with the resulting consequence that generating hexahedral meshes can be extremely difficult to perform and automate and the process often takes several orders of magnitude longer in time to complete than current methods for generating tetrahedral meshes. In this work, we present methods for ...

A 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...
