A space for simulation related technical resources and discussions.
Working with realistic design challenges is always rewarding, especially when it comes to showcasing the full power of Altair’s solutions. In this new tutorial, we dive deeper into HyperStudy’s advanced optimization capabilities as a sequel to our "Getting Started with PSIM & HyperStudy" tutorial, where we introduced…
Ski season is almost here, marking the return of shredding with your friends and family, cozying up in the lodge, and the smell that permeates your apartment after many weekends of not properly drying your gear. I decided to take action on the third, starting with my ski mittens. There are various off-the-shelf options for…
When running system simulations in Altair Twin Activate, it’s often useful to run multiple simulations, whether it’s for validating a system’s response to different phenomena, to perform statistical analysis or just to get a better grasp of how a parameter affects the overall response of a system. This small demo shows the…
Altair PSIM is a simulation and design software for power electronics, motor drives, and power conversion systems. Altair Compose is an environment for doing math calculations, handling data, automating workflows and much more. A new, powerful, library has been released on Compose from v2022.3 onwards, the PSIM Integration…
Introduction The original article is this, This article explains how to determine the cause of an error when the engine _0001.rad fails to run to the end. This is my own method, and it is not the best or the only way to find the cause of the problem. You can modify my methods and find your original better way. Methods A,…
Managing solver child processes in HyperStudy Hello HyperStudy users, When integrating non-HyperWorks solvers with HyperStudy, there can be instances that the non-HyperWorks solver integrated with HyperStudy does not have the required solver input arguments specified in the solver batch script to control the child…
Overview This article describes a model for confined blast simulations. A TNT charge is detonating inside a box with a small opening. A NRF boundary is used to model an infinite surrounding air domain. User-defined parameters for TNT positioning and mass are introduced. Finally, a HyperView session .mvw file has been…
The INIEVO criterion allows a two-step failure approach, divided into an initiation phase, in which damage has no effect on the stress computation, and a damage evolution phase, in which a stress softening can be generated. Ductile material behavior can be modelled in Optistruct with Damage Initiation DMGINI, and Damage…
Hi Altair EDEM community Running EDEM via command prompt is a very powerful way of running and exporting data efficiently. For automated analysis of multiple cases, not just data export, you can look at EDEMpy and we have examples of these in the EDEM calibration kits. For optimisation of multiple runs we can look at the…
Simulation Files and tutorial PDF download link * EDEM 3100 Slatted Conveyor with Concave Polyhedrals.zip Tutorial Overview In this tutorial, you will learn how to create a family of equal parts that move in the same trajectory but with a delay from each other. This is important to easily created many geometries moving in…
