Geometry clean-up is usually treated as a chore that stands between the CAD export and the interesting part. It deserves a different reputation. Taking the time to prepare a…
Splash lubrication in an EDU (Electric Drive Unit) is a harder problem than it looks. The oil has to reach the rotor bearings, coat the winding surfaces for heat dissipation, and…
Splash lubrication in gearboxes looks straightforward until you try to simulate it accurately. The gears spin, the oil flies, and the surfaces that need lubricant are never the…
Simulating oil distribution inside a spinning e-motor takes seconds. Predicting how component temperatures evolve under real operating loads takes minutes. Those two timescales…
With advancements in electric vehicle (EV) technology, the power density of drive motors has significantly increased, intensifying the challenge of effective thermal management in…
In computational fluid dynamics (CFD), spatial discretization, specifically the process of mesh generation and partitioning, plays a critical role in determining the accuracy and…
The particle method discretizes fluids or solids into discrete computational units, known as particles. For solids, geometric information is represented by triangular surface…
In computational fluid dynamics (CFD), there’s more than one way to describe how fluids move, mix, and interact with their environment. For decades, the finite volume method (FVM)…
shonDy is a three-dimensional multiphysics numerical simulation software based on the mesh-free particle method. This software eliminates the constraints imposed by complex meshes…
Modern Electric Vehicles (EVs) demand precise and reliable thermal management to ensure performance, safety, and longevity. However, traditional physical temperature sensors such…
In the previous article, we introduced the fundamental principles of the Lumped-Parameter Thermal Network (LPTN) method and demonstrated how it can be used to model heat transfer…
In product concept design, it is vital to comprehend the overall temperature profile of the product and the energy transfer between its components, rather than solely focusing on…
