A space for simulation related technical resources and discussions.
Energy storage and generation are increasingly important as the grid becomes more distributed and renewable energy sources make up a greater share of power generation. Our users use our battery and photovoltaic (PV) models for microgrids, satellite power flow simulations, electric vehicle (EV) drive trains & more. All of…
How to Model a Fuse in PSIM Modelling a fuse in PSIM is an extension of modelling a variable resistor. We use can use a controlled current source and Ohm’s Law, V = IR, or V/R = I. In this way we just need to define R = f(x,y,z, etc). For a fuse R will either be a nominal on resistance or an open circuit modelled by a very…
This article intends to describe the main changes that have been brought from 2019 to the contact entities in Abaqus user profile. SURFACE organization In previous versions, Abaqus contact surfaces (*SURFACE) were defined as a group entity. From version 2022 Contact surface are defined within set entity in new interface…
Road cyclists use plastic cleats on the bottoms of their shoes to create a constant point of contact between their feet and the pedals while riding. These cleats are adjustable to accommodate different user’s preferences, and must also resist a combination of compression (downstroke) tension (upstroke) and twisting forces…
Altair Compose is a powerful engineering math toolbox and you can script inside it to make your work more efficient. However, to fully master Compose, you must know how to incorporate it into your workflows even without its user interface and, more importantly, be able to leverage its capabilities regardless of it being…
Hi all, We have a new Instructor Led Training offering about “Electromechanical device modeling v2022.3”. For more comprehensive information about “Electromechanical device modeling v2022.3”, please visit the Altair Learn site (https://learn.altair.com/) under Class Schedule to check for scheduled sessions and register if…
Introduction Extensions are a way to customize your Altair applications and to seamlessly include your scripts into the graphical user interface (GUI). In this blog I will focus on HyperMesh (HM) and will touch on HyperView (HV) and HyperGraph (HG), but other Altair Products also use extensions for customization. I will…
New Feature in Feko 2023: Characteristic Basis Functions Method (CBFM) In the recent Feko 2023 release a new Simulation Method CBFM has been introduced. CBFM stands for Characteristic Basis Functions Method, and it is based on the use of Macro Basis Functions. The CBFM can be seen as a modification of the conventional…
Increase your PSIM simulation throughput and increase your CPU utilization with scripting A common question is how to increase the CPU utilization when running PSIM simulations. The simple answer is that one PSIM simulation runs on 1 CPU. If you want to use more CPU bandwidth then run more simulations. The reason for this…
Altair HyperView supports reading of multiple CAE results file formats for post-processing and has an additional capability to read generic ASCII results generated from any in-house or propriety codes deployed at customer’s organization. Altair ASCII format(*.hwascii) is the generic data format which aims to ensure…
