Novel fluid simulation software enables longer range for EVs by reducing losses in drivetrain

By mmillikin Driveline engineering consultancy Drive System Design (DSD) has partnered with software specialists Altair and FluiDyna to develop and enhance FluiDyna’s computer modeling technique, nanoFluidX, that significantly improves the analysis of lubrication flow. nanoFluidX utilizes a Smoothed Particle Hydrodynamics (SPH) methodology and increases the accuracy of analysis while reducing the simulation time from weeks to just a few days, when compared to traditional methods.

Smoothed-particle hydrodynamics (SPH) is a numerical method used for simulating the dynamics of continuum media, such as solid mechanics and fluid flows. Originally invented for astrophysical problems, it can also be successfully applied to free-surface flows and
