A space for simulation related technical resources and discussions.
In OptiStruct, Multi-Model Optimization (MMO) is a technique that can be used to optimize models that have different configurations for a similar design space. Examples for this would be models with shared common structure, but in different states such as open and closed doors, as well as models with separate modules that…
Frequency selected surfaces (FSS) are periodic surfaces with identical two-dimensional arrays of elements arranged in a multilayer dielectric substrate. They form a 3D-filter for incident electromagnetic plane waves and transmit or reflect them for different frequency ranges. A typical example is the sub-reflector design…
The analysis methods for describing the equation corresponding to the electrical circuit (mesh current method in Flux 2D and method of the node integrated potentials in Flux 3D) does not allow the representation of a Y–connected three-phase current source by its real schematic. This problem can be overcome by removing one…
This set of data will be of interest for you when you are familiar with legacy versions of HyperWorks and want to start using the new interface (here: in version 2021). However, it is intended especially for complete beginners with the software. After having worked through it, you will be familiar with the basic concept of…
In our rapidly evolving technological landscape, the need for high-performance integrated circuits (ICs) has soared, driven by the explosive growth of the Internet of Things (IoT), autonomous vehicles, and artificial intelligence (AI). These applications demand ICs capable of processing enormous data volumes swiftly and…
In this article, we provide step by step modeling guide for aerodynamics simulation for sedan car.
In a PSIM schematic shown below, the user reported the erroneous delay time at the output of the “Unit Delay”. In this schematic, Sampling frequency in the “Unit Delay” block is “1/100nsec”. The expected delay is 100nsec. The simulation result of this circuit is as below. The delay time is 150nsec instead of 100nsec. Is it…
S-FOUNDATION performs a series of different rigid and flexible code-checks on foundations, which are heavily influenced by not only the acting forces and the foundation's geometry, but also, the existing soil properties. Join us to learn how these results may vary considerably for two identical pile caps, and how the pile…
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…
