1. Introduction The shear cell is the gold standard bulk solid flowability characterisation test for quasi-static flow regime applications where the consolidating pressures are high and/or the strain rates in the bulk solid are low [1]. Examples include silo and hopper discharge as well as compaction systems like tablet…
This article demonstrates a high fidelity approach for the prediction of the static structural response of bulk solids handling systems that combines Discrete Element Method (DEM) modelling in Altair EDEM with Finite Element Method (FEM) modelling in Altair OptiStruct and Altair SimSolid. All requisite model files can be…
1. Introduction All the requisite files for the case study can be downloaded here: * GenericMixerOptimisation.zip Continuous mixing is increasingly adopted in the bulk solids processing industries due to its higher efficiency relative to traditional batch mixing unit operations. However, the complex mechanics of continuous…
RSP/RPC Files as Loading for Transient Analyses Since 2023.0 version of OptiStruct, the RSP file can be used as loading and OptiStruct internally manages transient loading. This relieves users from the need to explicitly define DAREA and TLOAD1 cards. * The ASSIGN,EXTLOD entry can be used to identify the RSP or RPC file…
The eLearning course, HyperWorks Customization & Automation, is now available on learn.altair.com! One of the most often requested advanced topics in HyperWorks is a class on the scripting layer incorporated in the HyperWorks suite of desktop applications (HyperMesh, HyperView). This class has been developed for someone…
The eLearning module, HyperStudy Flux Connection, is now available on learn.altair.com! In this module, we cover how to connect Flux to HyperStudy and use them together. This module is broken down into a short introduction and a demonstration on how to set up the connection between Flux and HyperStudy. Then some best…
Hi all, We have a new Instructor Led Training offering about “WinProp Introduction”. For more comprehensive information about “WinProp Introduction”, please visit the Altair Learn site (https://learn.altair.com/) under Class Schedule to check for scheduled sessions and register if you are interested. Otherwise, you can…
One frequent question on HyperGraph is how to create a Force vs Displacement curve. By default, HyperGraph uses the time vector for the x-axis. We can also use other results for the x-axis. For example, displacements to plot a force versus displacement curve. To do this: Open a result file in HyperGraph, via Menu, Icon, or…
There are situations in which you need to change the edge length of an element, or the distance between two nodes. For example, to improve the mesh quality or to achieve a better representation of the topology. In HyperMesh we can do this by selecting the Dimensioning option in the Measure Tool. The measured distance and…
Altair Radioss is leading code in scalability; its efficiency is demonstrated up to several thousands of cores. Altair Radioss proposes 3 different parallel computing methods: * Shared-Memory Parallelism (SMP). * Single Program Multiple Data (SPMD) or Massively Parallel Program (MPP). * Hybrid Massively Parallel Program…
