Table 7 Comparison of the mesh generation effort between GRA and GRAMC normalized to one rotation of the wheel and full simulation time

From: CFD simulations of gearboxes: implementation of a mesh clustering algorithm for efficient simulations of complex system’s architectures

Remeshing algorithm GRA GRAMC Net gain % Full simulation net gain %
Parametric value (1 rotation of the wheel) t \( \frac{t}{Z} \) \( \left(1-\frac{t}{Z}\right) \)
Spur gear 172.5 min 7.5 min 95.65% 14%
Helical gear 2400 min 100 min 95.84% 68%
Spiral bevel gear 2880 min 120 min 95.84% 72%
