A space for simulation related technical resources and discussions.
The extension provides a powerful, free editor VS code for the OpenMatrix Language, an open-source computational programming language. This brings features like syntax highlighting, indentation rules, collapsible/folding and advanced features like inbuilt dynamic auto-completion, plotting and visualization capabilities of…
PSIM Legacy License Changes After the acquisition of PSIM by Altair in 2022 it was decided to simplify the functionality choices of PSIM and include more functionality into 4 basic configurations: Power supply, code generation, co-simulation, motor drives. These replace the old modules: motor drive, digital control,…
When dealing with a Radioss simulation, there are two main types of outputs: * Animation files are mainly used to display results as contours on the model. * Time History (TH) files that are used to plot curves – usually versus time, but it can also be with respect to another result (displacement) – of a given result for a…
In this document, Hyperelastic analysis using OptiStruct is presented with a comparison of different material models and 4 applications involving Hyperelastic material. Details are given in the PDF file that is separately attached. Since animations are not included in the PDF file, they are embedded in the article body…
The purpose of this document is to showcase some of the capabilities of OptiStruct explicit analysis. The intention is not to present an exhaustive set of examples covering all the capabilities. Some commonly used applications like analysis of Hyperelastic materials and snap fit analyses are presented. Three examples are…
In newly released version PSIM2023.0, if it is installed with a legacy license, the display of library browser display window has a problem: many elements are missing. Actually, those elements are not missing from the PSIM library. They are missing only from the display window of the library browser. The workaround is to…
This example simulation shows PSIM being used to control a grid link 3-phase inverter with real and reactive power control. Control in the dq reference frame is being implemented. The control scheme allows for real and reactive power to flow from the DC bus to the grid or from the grid to the DC bus. This simulation…
The magnetic elements in PSIM (windings, leakage paths, air gaps, and magnetic cores) provide a powerful way of modeling magnetic devices. The objective of this tutorial is to show how to define the saturable core element. Parameter Definition of the Saturable Core Element The saturable core element is under the menu…
In this simulation Field Orientated Control, FOC, of an Induction motor is implemented on PSIM. There are several important aspects of the simulation: The power stage, which is characterized by the red traces which includes: * The DC voltage source * The 3-phase inverter * The induction motor model * The mechanical…
Altair's SpiceVision PRO - Helping chip designers at the SPICE level. Introduction- SPICE (Simulated Program with Integrated Circuit Emphasis) is an open-source analog electronic circuit level simulator. SPICE circuits and models are common in the Electronic Design Automation (EDA) world. They are generated by many EDA…
