| ● | Precision ?PrecisionGood enough for engineering use. The pressure drop is steady within under ±0.1 % (last 200 iterations); mass balance 0.00 %. The remaining unsettledness is mostly next to the walls. | good enough for engineering use |
| ● | Stopped | Stopped at iteration 302: converged (the pressure drop steady within ±0.0 % over 200 iterations, residuals low). |
| ● | Pressure drop ?The ± on a resultHow much it moved over the last 200 iterations. ≤ ±1 %: good enough for engineering use · ±1–3 %: trends and comparisons · above ±3 %: not settled yet. The mesh's own error is not in it: Check the mesh for that. | < ±0.1 % |
| ● | Mass balance (inflow vs outflow) ?Mass balanceInflow against outflow: below 0.5 % means the flow field is consistent. A larger gap: the run has not settled, or the mesh leaks at an opening.below 0.5 % = the flow field is consistent | 0 % |
| ● | Where it is still settling ?Where it is still settlingThe part of the flow that still changes between iterations; the 3D view colours it (Colour → Where still settling).the 3D view colours it: Colour → Where still settling | The remaining unsettledness is mostly next to the walls. |
| ● | Residuals at the end ?ResidualsHow much the solver's equations are still out of balance, scaled. Low (below 10⁻³) or no longer falling, with steady key results, means the run is done. A hint; the ± on the key results is the measure that counts.Residuals measure how far the solver's equations are from being exactly satisfied in each cell; they shrink as the solution settles. Here they levelled off below the usual 10⁻⁴, so the flow field has settled. The key result moved by under ±0.1 % over the last 200 iterations, so it is settled. | pressure 1.2e-07 · velocity 5.1e-06 |
| ● | Cells ?CellsThe number of cells the flow was computed on. More cells: finer detail and less mesh error, but a longer run. Draft is for set-up checks and trends, Standard for numbers you report, Fine to confirm them. | 204 600 |
| ● | Mesh level ?Mesh levelDraft and quick look give trends; Standard is for numbers you report; Fine confirms them. | Standard |
| ● | Max non-orthogonality ?Non-orthogonalityHow far the line between two cells' centres leans away from the face between them (0° = square on). Below 65°: good. 65–75°: fair, the solver corrects for it. Above 75°: poor: less accurate gradients, slower to settle, sometimes a blow-up. If poor: a finer mesh where it happens (sharp edges, thin gaps), or fewer wall layers there.below 65° good, above 75° poor (less accurate, slower to settle) | 27° |
| ● | Max skewness ?SkewnessHow far the face between two cells sits from the midpoint of the line between their centres, relative to the cell size. Below 4: good. 4–8: fair. Above 8: poor: values on the faces are interpolated wrongly. If poor: a finer mesh near curved walls and small features, or smooth tiny details away in Inventor. | 0.2988 |

| ● | Wall layers ?Wall layersThin cells stacked along the walls, where the speed changes fastest. Fewer than planned show up at sharp edges and complex corners: friction and heat transfer there are less accurate.thin cells along the walls; fewer than planned where the surface is sharp or complex | 3.0 of 3 on average |
| ● | y⁺ on the walls (mean) ?y⁺ on the wallsThe first cell's distance from the wall in viscous units. The wall functions used here want about 30–300; below 5 also works with k-ω SST; 5–30 is the least accurate band.the wall functions used here want about 30 to 300; below 5 also works with k-ω SST; 5 to 30 is the least accurate band | 7.373 (min 7.046, max 11.07) |
