报告摘要：With the rapid progress of computers and other digital technology, computational analysis has become indispensable in tackling large-scale complex problems faced by modern engineering and in the digital transformation of industry. This talk presents our recent research towards developing a computational framework that fully automates the engineering analysis process directly from commonly used formats of digital geometric models. Our approach is underpinned by the scaled boundary finite element method, which enables us to incorporate an octree algorithm for automatic mesh generation across various formats such as digital images, STL models, point clouds and traditional CAD models. Furthermore, the solution procedure is purposely designed for the scaled boundary finite element method to leverage modern computer hardware architectures for high-performance computing. Numerical examples and demonstrations illustrate key features and the potential of the proposed framework for simulating complex 3D models, accounting for material and geometric nonlinearities, fractures, and contacts.
