Solver settings for the 2D ABL flow.
| Turbulent model | Standard k–ε model with standard wall functions |
| Boundary conditions | |
| Inlet | UDF for U, k, ε |
| Outlet | Pressure-outlet with zero pressure |
| Top | Symmetry |
| Ground | ks = 0.2, UDF for Cs |
| Ground-pitch and stadium entrances | ks = 0.58758, Cs = 0.5 |
| Cell zone conditions | |
| Fluid: top layer | Source term, x-momentum = 0.089 N/m3 |
| Solution methods | SIMPLE; second order for pressure, momentum and turbulence transport equations |
| Convergence criterion | None (to control end of calculation) |
