A space for simulation related technical resources and discussions.
Validation of CEM codes is essential if they are to be used in production analysis and design. The utility of CEM modeling is greatly diminished without trust that a given code produces answers sufficiently representative of physical reality. This topic was the focus of the recently published IEEE Antennas and Propagation…
In this article, we demonstrate the implementation of bidirectional position control for a BLDC motor under variable load conditions. A custom simulation model has been developed, where both the desired position and external torque load can be provided from 3D mechanical systems. Since PSIM is inherently a 1D system-level…
The aim of this article is to demonstrate how to define the Preload Axial force applied to the set of beam, truss and spring elements. This feature is available from Radioss version 2024 Software used: Altair Radioss version 2024.1 & above Altair HyperMesh version 2025.1 Model setup We considered five different types of…
The aim of this article is to show the different type of sequence of drops and step by step procedure used in model setup by using HyperMesh and Radioss solver. Why This sequence of drops is done on a single part / assembly to validate it for the shocks what it may face during it lifetime or while transporting from…
The aim of this article is to demonstrate the steps involved for material (and properties) encryption with curves and failure using Altair HyperMesh version 2022.3 (New and Legacy). Applications Secure material testing data (stress-strain curves, failure limits) or knowledge (springs stiffness, etc.) The material laws can…
In this article we will explain how to set up the optimization of Kp (Proportional Gain) and Ti (Time constant) for average current control of Buck Converter with PSIM and HyperStudy. PSIM Set-up The PSIM schematic is composed of three main parts as shown in Fig1: Buck converter with Ideal switching devices: PI Controller…
Custom functions written in Python or Compose OML can enhance your HyperStudy workflows by enabling more flexible response definitions. While HyperStudy is a code-free platform designed to handle simulation automation, that doesn't mean you lack the flexibility to add your own custom functions! This guide shows you how to…
Following the series of PSIM Community articles on variable passive components, this article discusses the creation of a variable resistor model. Compared to the Variable Inductor and the Variable Capacitor models, this implementation is much simpler. Essentially, we can leverage the Nonlinear Element block to implement…
Overview: Altair MotionSolve and MotionView, Altair’s multibody solutions, offer enhanced usability and flexibility in multibody modeling, simulation, visualization, and optimizations. New real-time capabilities for ground vehicles reduce time to market by providing rapid and accurate model development, allowing engineers…
A common question regarding the thermal model is if it allows for soft switching simulations. In this article, we’ll take a look at how soft switching works with thermal models. If you want to know how PSIM calculates and scales losses with temperature, voltage, current and Rg, please take a look at this article: Altair…
