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…
Squeaks and rattles are unwanted noises that are directly related to the perceived quality of a product. In this video, you will see how to identify and eliminate such issues using a simulation-driven approach with Altair SimSolid. CAD geometry, loads and solved model can be found attached to this article. Conclusions: -…
MotionView/MotionSolve is a comprehensive multibody simulation software that helps you easily build and execute complex system models to evaluate the dynamic response of products and optimize their performance. With it, engineers and designers can graphically build system models describing the phenomena of interest. These…
Exporting an entity set to a solver deck can lead to a very long id list. For that reason, some users prefer to define a set of nodes or a set of elements through a combination of formulaic expressions. This can be done in HyperMesh as explained below. * From the Model Ribbon select Sets * From Set Type select formula *…
