市場存在很多關於 5G 的炒作。圍繞更快、更互聯的未來的聲音令人興奮，但對於許多產品設計師而言，5G 的確切定義並不清晰。

Altair 和 Rolls-Royce Germany 的合作將應對各種用例，包括將資料科學應用于大量工程測試資料，這可以顯著減少所需的感測器數量。

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.
