Dynamically adaptive computational grids allow for the simulation of significantly larger domains in space and time. Tree-structured grids are particularly memory-efficient and easy to parallelize. The challenge is adopt such grids in a minimally invasive way for existing simulation software without loosing too much of their inherent efficiency. D.8 develops and implements such an integration concept for examples within the SFB. This requires new developments in terms of modelling, discretization, data structures and data access, parallelization, and visualization.

动态自适应计算网格允许在空间和时间上模拟更大的域。树状结构的网格特别节省内存，并且易于并行化。挑战在于以一种微创的方式为现有的仿真软件采用这种网格，同时又不会失去太多固有的效率。D.8为SFB内的示例开发并实现了这样的集成概念。这需要在建模、离散化、数据结构和数据访问、并行化和可视化方面有新的发展。
