Development of methods for storage of simulation results from discrete element method

这个项目的主要目标是开发先进的方法来存储模拟结果，这些结果是用离散单元法(DEM)对颗粒材料建模后获得的。与现有的传统方法相比，新的概念应该可以在几倍的时间内减少存储的数据量，避免有意义的信息丢失。从长远来看，所获得的知识将成为提高微尺度数字高程模型模拟的准确性和整体效率的必要步骤，这是由于关于模拟颗粒材料的更精确的时空信息；使在相同的磁盘空间中存储更大数量的模拟成为可能；-提高数字高程模型在固体加工工程领域的适用性。

The main objective of this project is the development of advanced methods to store simulation results which are obtained after modelling of granular materials with the discrete element method (DEM). In comparison to conventional methods which exist nowadays, novel concept should allow to reduce amount of saved data in several times and to avoid the loss of meaningful information. In a long term, the acquired knowledge will: - serve as an essential step to increase accuracy and overall efficiency of microscale DEM simulations due to more precise spatio-temporal information about modelled granular materials; - make it possible to store a much larger amount of simulations on the same volume of disk space; - improve applicability of the DEM in the area of solids process engineering.
