A new study on physics-informed neural networks (PINNs) for fluid dynamics simulations reveals complex interaction effects between different training techniques. While many proposed methods show little improvement in isolation, combining periodic activations with causal weighting significantly enhances accuracy for simulating vortex shedding in Navier-Stokes equations. However, adding more techniques can lead to performance degradation, indicating that not all interventions are complementary and that more complex training recipes are not always superior. AI
