    • DEM particle characterization by artificial neural networks and macroscopic experiments 

      Benvenuti, Luca; Kloss, Christoph; Pirker, Stefan (CIMNE, 2015)
      Conference report
      Open Access
      The macroscopic simulation results in Discrete Element Method (DEM) simulations are determined by particle-particle contact laws. These usually depend on semi-empirical parameters, difficult to obtain by direct microscopic ...
    • Determining the coefficient of friction by shear tester simulation 

      Aigner, Andreas; Schneiderbauer, Simon; Kloss, Christoph; Pirker, Stefan (CIMNE, 2013)
      Conference report
      Open Access
      The flow behaviour of very dense particle regimes such as in a moving or fluidized bed is highly dependent on the inter-particle friction, which can be characterized by the coefficient of friction. Since only rough guide values ...
    • Energy balance in a particle system 

      Mayrhofer, Arno; Hager, Alice; Kloss, Christoph (CIMNE, 2017)
      Conference report
      Open Access
      The energy distribution inside a particle system can be used to study the mechanical properties of such a system and its response to external perturbations. In the present article, the energy terms for typical discrete ...
    • Parscale - an open-source library for the simulation of intra-particle heat and mass transport processes in coupled simulations 

      Radl, Stefan; Forgber, Thomas; Aigner, Andreas; Kloss, Christoph (CIMNE, 2015)
      Conference report
      Open Access
      We introduce the open-source library ParScale for the modeling of intra-particle transport processes in non-isothermal reactive fluid-particle flows. The underlying equations, the code architecture, as well as the coupling ...
    • Strategies for simulation software quality assurance applied to open source DEM 

      Amberger, Stefan; Goniva, Christoph; Hager, Alice; Kloss, Christoph (CIMNE, 2011)
      Conference report
      Open Access
      We present a strategy to improve the software quality for scientific simulation software, applied to the open source DEM code LIGGGHTS [1] [2]. We aim to improve the quality of the LIGGGHTS DEM code by two measures: Firstly, ...
