One of the most common questions from prospects and new users is, what is the difference between Altair Flux and FluxMotor. In this article an introduction to Flux and FluxMotor will be provided and then the difference between the two tools will be compared for different aspects. Definitions: Altair Flux is a general…
SimCoupler fuses PSIM with MATLAB/Simulink by providing an interface for co-simulation. Part of a system can be implemented and simulated in PSIM and the rest in Matlab/Simulink. It’s straightforward, easy to set-up and requires minimal user input. With SimCoupler, there’s no need to choose between tools. Use both and…
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…
