A space for simulation related technical resources and discussions.
Numerical EM simulation is an established approach to optimize and validate designs for reflector antennas. For electrically large structures, however, memory requirements and runtimes can become quite extensive. In this paper we show recent improvements of MLFMM (Multi-Level Fast Multipole Method) implementation in Altair…
Inverter's Average Model: A Streamlined Approach The average model of an inverter represents a distinct approach compared to ideal or thermal models. This model is designed to expedite simulations by omitting the detailed switching phenomena. By focusing on the overall behavior rather than individual switching events, the…
Problem Statement The increment of renewable energy sources has introduced issues that concern the integration of them in the electric grid without influencing its stability. This new challenge on the way to electrification has created a need for capturing transient phenomena in a short - time simulation. The further…
Computational time has always been one of the most important aspects of DEM Modelling. Initially, it could be assumed that having an accurate and realistic material model through material calibration is the main target. If you want to learn about material calibration, read this post: However, even though calibration is…
As part of the AEC Global Technical Team (GTT) strategies for this year, it was decided to perform short webinars covering some topics that might not be extensive enough for a 1-hour discussion. April 24th was the starting date to perform these short webinars. Presenting the event called "Using S-CALC section properties…

We are just 1 week away from our first global ATCx AEC, a one-day virtual event dedicated to transforming the architecture, engineering, and construction (AEC) sector. After the main session, don’t miss the Facades track—an opportunity to dive deeper into the latest digital innovations transforming facade design. Explore…
A significant proportion of food produced globally is never consumed, with around 14% lost between production and retail [1]. While food loss can occur at various stages of the supply chain, improving bulk material handling in food processing—through virtual testing and system optimization—can help reduce losses and…
Flow Simulator (FS), like many iterative solvers, can have convergence issues. This discussion provides some information on the FS solver and provides some suggestions to address convergence issues. Introduction The FS solver uses an iterative procedure to solve for the element flow rates and nonboundary chamber pressures.…
Adding C functions to your Altair Embed model is simple using the "Extern Definition" block and "Extern Function" block. The Extern Definition block lets you supply any legal file scope C syntax, such as structures with initializers, #includes, #pragmas, typedefs, arrays, and function definitions. The Extern Function block…
