A space for simulation related technical resources and discussions.
For Part 1, see here: https://community.altair.com/discussion/64350/buckling-studies-of-a-short-span-steel-girder-bridge-part-1 What Have We Learned: The Nonlinear Static analyses, an inherently more accurate analysis type than the P-Delta types, predicts that buckling will occur at approximately 5x of the “Dead + Self…
This document aims to introduce the various ways one can study buckling behavior in S-FRAME. We will examine this using a generic steel girder bridge structure, which has been deliberately altered to weaken it, hence allowing us to illustrate buckling behavior. The modifications from the original design include: Reduction…
The need for fibers in EDEM Fibers are fundamental in some industries like Agriculture, Construction, Fabrics Manufacturing or Battery Manufacturing, among others. EDEM has been used in the past in simulations within these fields, but it did not offer a model specifically designed for fibers. The Fibers Bonding model is a…
Enabling GPU for PhysicsAI 2025.1 version on a Linux machine Hello PhysicsAI users, When using PhysicsAI 2025.1 version on a Linux machine, cuDNN 8.9.7 version needs to be installed on the machine. CUDA Toolkit 11.8 version remains the same. If cuDNN 8.7 version is used along with CUDA Toolkit 11.8 on a Linux machine for…
This post presents an Altair Radioss solution to simulating hypervelocity impacts on composite laminate. It is based on Meso-scale modeling of hypervelocity impact damage in composite laminates from Aleksandr Cherniaev & Igor Telichev, published in Composites Part B: Engineering, volume 74 (June 2015) [1]. Figure 1: Bullet…
Plastic gears are widely used in automotive, industrial, and consumer applications due to their cost-effectiveness, low weight, corrosion resistance, and quiet operation. In the automotive industry, plastic gears can be found in critical subsystems such as windshield wiper mechanisms, seat adjusters, electric window…
The goal of this article is to demonstrate how to use Altair OptiStruct explicit capabilities to perform a rollover protective structure (ROPS) analysis. In the attached presentation, users can find the model details and results. This article includes: A ready-to-use Altair OptiStruct model Altair HyperMesh v2025.1 Altair…

Authors: Ambrish Singh and Spyridon Mallios 1.0 Introduction A Discrete Element Method (DEM) simulation can provide critical insights into the behavior of granular media subjected to various environmental, process, and operating conditions. However, prior to modeling process of interest, ensuring that the DEM simulation…
