The ‘Digital Twin’ in Hardware in the Loop (HiL) Simulation: A Conceptual Primer

Michael Grieves first uttered the term ‘digital twin’ in 2003, and since then much ink and many pixels have been spilled over it. We’ll keep it relatively brief. While ‘digital twin’ can mean many things to many people, it has a more restricted set of understandings when we speak in the context of real-time simulation and/or Hardware in the Loop (HiL) testing. To begin to explain this closer-cropped meaning, let’s start by thinking of a […]

User Explainer | Remote Use of OPAL-RT Simulators & Platforms

Despite the current global fight against COVID-19, OPAL-RT continues to work hard in serving its customers with the best operational efficiency possible. With the amazing collaboration of our own employees—and thanks to our stellar IT department—we’ve succeeded in requiring less than 48 hours to optimize our own remote work. All of our users—Academic/Research, Industrial—can achieve the same if they’d like, thanks to the combined use of: Virtual Private Network (VPN)Remote Desktop Protocol (RDP)Collaborative and web […]

OPAL-RT Serves up Steaming Hot Espresso: Coffee-in-the-Loop (CIL)!

Café-in-the-Loop Adapted from Christian Dufour at https://coffee.christiandufour.ca/2020/01/cafe-in-loop.html Ph.D. and Senior Simulation Specialist, Power Systems and Motor Drives, OPAL-RT TECHNOLOGIES This personal project has as its goal the improvement of my morning espresso made with my small yet very faithful 16-year-old Saeco Aroma espresso machine. It is still in a perfectly functional state having required absolutely no repairs, and in this way makes me think of my 2000 Camry. In order to do this, I cabled […]

MuSE: Clustering, Extensibility & Almost Infinite I/O Power with OPAL-RT Simulations

OPAL-RT has improved the user experience when using multiple simulators, remote targets or when requiring clustered machines for increased I/O or other capabilities. This high-speed link is referred to as MuSE (Multi-System Expansion link).Irène Pérès, MuSE’s Product Owner at OPAL-RT, recently joined us to speak about the incredible power, flexibility, versatility and user-friendliness of this special add-on—that is so much more than just an expansion kit.Interviewer (IV): Thanks for joining us, Irène! I have a partial […]

eHS: The Nanosecond Power Electronics Solver Whose Time has Come

What is eHS: The Nanosecond Power Solver?“The OPAL-RT electric Hardware Solver (eHS) is a powerful floating-point solver… that enables users to simulate an electric circuit on an FPGA automatically, without having to write the mathematical equations.”“It combines the simplicity of building electric circuit models using the new OPAL-RT Schematic Editor, SimPowerSystems Toolbox, PSIM, the PLECS Blockset, or NI Multisim software with the strength of OPAL-RT FPGA-based simulators to solve the currents and voltages within the […]
