A space for simulation related technical resources and discussions.
Altair Activate is an environment for block-level diagram modeling and system-of-systems integration, useful for simulating at different levels of fidelity, from simple signal-based modeling to robust Multiphysics applications and digital twin solutions. In this first challenge, you will learn how to build and execute a…
Introduction: In this article, we review three different modeling practices for performing an FRF analysis by enforcing acceleration to the structure. The methodologies are simulating the phenomenon of enforced acceleration with the use of the following three cards: * SPCD * ACCEL1 * GRAV Frequency Response Analysis is…
The units set at the two last lines of /BEGIN can have several roles : 1. Unit conversion of the input parameters If the two lines are different (not matching), Radioss will consider that the input data (the input model) are defined using the unit system set at the first line and will perform a unit conversion to the unit…
Product = GENESIS This custom-made aerospace case study demonstrates what can be done with any assembly, part, or structure of an aircraft. This is a fuselage section on which sizing (thickness changes) and topology (shape changes) were used to optimize the structure for a couple of very simple load cases; cabin pressure…
Attached are EDEM Benchmark results from 2019, 2021 and EDEM 2022.2. The latest benchmark results are in EDEM_GPU_Benchmarking_2022.2.pdf These results are from a series of standardised real world simulations: The key results show the scalability of the A100 GPU (CUDA Solver) vs CPU:
AEC Coffee-Break Series Dynamic behavior is an essential structural characteristic that structural engineers should consider. The effects of dynamic loads (earthquakes, blasts, vibrations, or any time-varying loading) are often greater than static loads and can vary in magnitude at non-periodical time intervals, increasing…
The OpenRadioss Community met in Aachen, home town of the SkyCab, on June 27th, with a full day of technical presentations and discussions around this exciting open-source project. https://altair-2.wistia.com/medias/uj70zppe7n First, I want to express my profound gratitude to our host the FH Aachen, University of Applied…
AEC Coffee-Break Series How do structural engineers prepare for unpredictable dynamic loads? Join us in this three-session coffee break series to learn how S-FRAME can be used to understand dynamic behaviors and apply loads to simulate these events. We will cover at a high level some fundamental concepts in dynamics, from…
The SimSolid computational engine is based on extension to the theory of external approximations. External approximations are a generalization of Finite Element Method (FEM) in terms that: * Absolutely arbitrary geometrical shapes can be used as “finite elements”. * Basis functions which approximate the field of interest…
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…
