Interested in understanding how your vehicle will perform on soft soil terrain? MotionView provides the capability to simulate soft soil roads and tires that engage with the terrain. This simulation can be applied to various vehicle types, including UTVs, semi-trucks, three-wheelers, cars, and small trucks. This video will…
Altair Compose is commonly thought of as an engineering math toolbox, a tool for handling computationally intensive operations, model complex systems in 0D, process data, etc. but Compose is an equally powerful tool when thought of as a driver of other tools’ simulations and the glue that connects all the simulations and…
Introduction: OSSmooth is a semi-automated design interpretation software, facilitating the recovery of a modified geometry resulting from structural optimization, for further use in the design process and FEA reanalysis. OSSmooth is embedded in HyperMesh and it can be used in three different ways: OSSmooth for geometry,…
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…
