On procedural urban digital twin generation and visualization of large scale data
Sanjay Somanath, Vasilis Naserentin, Orfeas Eleftheriou +3
The desired outcome for urban digital twins is an automatically generated detailed 3D model of a building from aerial imagery, footprints, LiDAR, or a fusion of these. Such 3D mode…
Space-Time CutFEM on Overlapping Meshes: Simple Continuous Mesh Motion
Mats G. Larson, Anders Logg, Carl Lundholm
We present a cut finite element method for the heat equation on two overlapping meshes: a stationary background mesh and an overlapping mesh that moves around inside/"on top" of it…
Digital twins for city simulation: Automatic, efficient, and robust mesh generation for large-scale city modeling and simulation
Vasilis Naserentin, Anders Logg
The concept of creating digital twins, connected digital models of physical systems, is gaining increasing attention for modeling and simulation of whole cities. The basis for buil…
A MultiMesh Finite Element Method for the Stokes Problem
August Johansson, Mats G. Larson, Anders Logg
The multimesh finite element method enables the solution of partial differential equations on a computational mesh composed by multiple arbitrarily overlapping meshes. The discreti…
Cosmic String and Black Hole Limits of Toroidal Vlasov Bodies in General Relativity
Ellery Ames, Håkan Andréasson, Anders Logg
We numerically investigate limits of a two-parameter family of stationary solutions to the Einstein-Vlasov system. The solutions are toroidal and have non-vanishing angular momentu…
MultiMesh Finite Elements with Flexible Mesh Sizes
August Johansson, Mats G. Larson, Anders Logg
We analyze a new framework for expressing finite element methods on arbitrarily many intersecting meshes: multimesh finite element methods. The multimesh finite element method, fir…
