市场存在很多关于 5G 的炒作。围绕更快、更互联的未来的声音令人兴奋，但对于许多产品设计师而言，5G 的确切定义并不清晰。

Altair 和 Rolls-Royce Germany 的合作将应对各种用例，包括将数据科学应用于大量工程测试数据，这可以显著减少所需的传感器数量。

This eBook describes the theoretical background behind the Discrete Element Method (DEM) - a particle-scale numerical method for modeling the bulk behavior of granular materials and many geomaterials such as coal, ores, soil, rocks, aggregates, pellets, tablets and powders. The following topics are covered: - Modeling Approaches - DEM Background - Particle Motion Calculations - Time Steps - Interaction Models - Contact Detection - Particle Shapes - Material Calibration - Geometries in DEM - Coupling DEM with other CAE tools

Ian Symington of NAFEMS investigates the accuracy of Altair SimSolid through a series of eight analysis benchmarks. Article originally published in Benchmark Magazine by NAFEMS, the International Association for the Engineering Modeling, Analysis & Simulation Community. Find out more at nafems.org.
