CFD
A branch of study that solves the governing equations of fluid flow by numerical methods. Its basic workflow includes geometry modeling, mesh generation, boundary condition specification, numerical solution, and post-processing analysis.
Timeline (last 90 days)
The medium-mesh computation diverged in the early stage, and the Agent autonomously located pressure oscillations above the airfoil surface and completed troubleshooting by changing the numerical scheme, using an incompressible sphere solution as a comparison, and fixing the cold-start issue.
Traditional numerical methods are slow but can guarantee that physical constraints are satisfied at the discrete level
Traditional CFD pursues controllable error and convergence guarantees, whereas AI methods trade statistical uncertainty for computational speed
Traditional CFD computation can take hours or even days, whereas inference with neural operators often takes only milliseconds.
CFD simulation is based on idealized numerical assumptions, whereas PIV experiments measure the motion trajectories of tracer particles in real flow fields.
The RealPDE competition introduces real PIV (Particle Image Velocimetry) and CFD (Computational Fluid Dynamics) fluid data.
The core challenge of the Sim2Real track is to generalize neural operator models trained on CFD data to real PIV data.
In a 3D CFD liquid simulation test using the SPH method, the project generated by DXU E4GA ran smoothly at a scale of 6,000 particles, achieving the best performance.
