simulation engines

Bentley says its upcoming electric cars will use orchestra recordings to simulate the deep sound of its classic V8 engines, aiming to preserve the brand's signature character as it moves away from combustion. The luxury automaker, which has committed to an all-electric lineup, is turning to musical instruments rather than synthesized engine noise to craft a distinctive sound for drivers.

A research team has used quantum computing to perform FLiBe chemistry calculations, according to the American Nuclear Society. FLiBe, a molten fluoride salt mixture of lithium and beryllium, is a leading coolant and fuel carrier for molten salt reactor designs. Accurate predictions of its chemical behavior are difficult for classical computers, making the work a notable step toward applying quantum methods to nuclear reactor design and simulation.

Zenithon has raised $10 million in funding to build AI world models capable of simulating extreme physics. The startup says such models could help researchers and engineers understand conditions that are difficult or dangerous to test in the real world, from high-energy environments to advanced materials. Details on investors and product plans remain limited so far.

Video game simulation engines are increasingly viewed as dual technologies, with uses stretching beyond entertainment into defence training, industrial modelling and research. The discussion, highlighted in an analysis by Polytechnique Insights, examines how engines originally built for gaming now power serious applications, raising questions about their strategic and commercial value.

A new installment of Project SkySim details how a single physics core can be run in three different modes, part of an ongoing series on building a simulation system. The article walks through the engineering choices behind keeping one shared physics implementation while supporting multiple execution paths, an approach aimed at flexibility and easier maintenance in simulation software.

A newly circulated paper recounts how Los Alamos scientists turned to the Eniac in 1947–1948 to run some of the earliest Monte Carlo simulations, using the pioneering computer to model nuclear processes through random sampling. The episode is widely seen as a founding moment of computational science, showing how wartime computing hardware was repurposed for peacetime physics research and helped establish a technique now used across finance, engineering and beyond.

Researchers have introduced a new quantum algorithm aimed at a key bottleneck in fluid-flow modeling, a computationally intensive problem in physics and engineering. The development suggests quantum computing could eventually speed up simulations of turbulence and fluid dynamics that strain classical supercomputers. Details on the team behind it and practical timelines remain limited.

The fourth instalment in a physics programming series is out, this time focusing on the physics update loop — the core step in game engines where forces, collisions and movement are advanced at a fixed rate. It continues a series that has been walking developers through the basics of simulating physics in their own code.
