Alternate Installerとは？ 製品をダウンロードする際、次の2種類のインストーラーが表示される場合があります。 「製品名＋バージョン」：Xpress Installer 「製品名＋バージョン＋Alternate Installer」：Alternate Installer Alternate Installerが用意されている製品では、通常の「製品名＋バージョン」のインストーラーをXpress Installerと呼びます。 Xpress InstallerとAlternate Installerの違い 両者の大きな違いは、必要なモジュールをいつダウンロードするか？です。 ● Xpress Installer…
In finite element analysis (FEA), the accuracy of your simulation is only as good as the input data - particularly the material properties. In safety-critical applications such as aerospace, defense, and automotive, using nominal or average material properties is not enough. These values don’t account for natural…
Hi PhysicsAI users, When performing prediction using inputs via ‘Global’ or ‘Nodal’ Hooks approach in PhysicsAI, the below mentioned considerations are important to be followed. The CAD or solver deck to be used for prediction should have an associated .json file named _predict_inp.json which should be saved in…
We recently released a new eLearning course, Virtual Die Tryout Analysis with Inspire Form. Explore tryout analysis for forming. Build the skills needed to set up and analyze complex multi-stage stamping processes with tools and blanks in Inspire Form. Learn about Virtual Die Tryout Analysis, at your own pace! Virtual Die…
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…
