TL;DR: The proposed multi-scale model forms a well-suited basis for realizing the collaboration concept, which allows several experts to simultaneously manipulate a shared infrastructure model on various scales while using the different design tools they are accustomed to.

TL;DR: This paper deals with fast and efficient algorithms to generate and process octrees - even on-the-fly - from surface-oriented models for applications in civil engineering, and obtains a reliable volume-oriented attributed model that can serve for numerical simulations as well as to determine relations between parts of the model to ensure global consistency.

TL;DR: A parallel data access framework with interfaces to all parts of the simulation pipeline such as pre-processing, numerical simulation, and post-processing has been developed and the applicability of this approach is shown by simulating urban flooding including surface flow of a city, the pipe network interaction, and its consequences to individual buildings.

TL;DR: In this article, it is shown that the essential ideas of FCM, i.e. exponential convergence at virtually no meshing cost, can be achieved in geometrically nonlinear setting, if high-order Legendre shape functions are replaced by a hierarchically enriched B-spline patch.

TL;DR: In this article, a parallelization strategy for the multi-level hp-scheme is presented that is adapted to the schemes simple hierarchical structure, by distributing the computational domain among processes on the granularity of the active leaf elements and utilizing shared mesh data structures.
