Glossary
Terms used in LoudGears and in these docs.
| Term | Meaning |
|---|---|
| Angular torque | The twisting moment applied to the wheel in the load case, in N·m. Shown as wheel or drive torque in results and reports. |
| Applied load case | The loads that were actually applied to a specific run. Shown on its result page. |
| B-Rep | Boundary representation: the exact surfaces and edges of your CAD model, as opposed to the analysis mesh. |
| Credit | The unit that pays for a verified analysis. Reserved when a run is queued, consumed by a verified result, released otherwise. |
| Device | A workstation with an activated ForgeNode. Your plan limits how many can be active. |
| Displacement | How far a point on the wheel moves under load, in mm. |
| Fitment Guide | The vehicle database LoudGears uses to supply load cases by make, model, and year range. |
| Fitment snapshot | The vehicle and load case saved to a project and bound to its next analysis. |
| ForgeNode | The LoudGears Windows app that prepares geometry and runs the solver on your workstation. |
| Hotspot | A location of locally high stress. The viewer marks the top five. |
| Manual override | Load and torque values you enter to replace the Fitment load case. |
| Operation ID | The identifier of one analysis run. Quote it when contacting support. |
| PCD | Pitch circle diameter: the diameter of the circle through the wheel's bolt holes. |
| Radial load | The force pressing on the wheel in the load case, in N. |
| Residual | A measure of how closely the solver converged. A numerical quality check, not the verdict. |
| Result fingerprint | A fingerprint of the signed result. If any value changed, the hash would not match. |
| Revision | One version of a wheel design within a project, with its own analysis runs. |
| Rear-wheel discount | Half price for the rear wheel of a front/rear pair with matching outer diameter (within 1.5%) and spoke count. |
| Staggered fitment | Front and rear wheels of different widths or sizes. LoudGears analyses both wheels of such a pair from one file. |
| Route | The analysis configuration a run uses: Standard (GPU, 5 mm) or CPU Standard (CPU, 5 mm). |
| Run input fingerprint | A fingerprint of a run's inputs. Identical inputs give the same fingerprint. |
| Safety factor | The simplified yield strength divided by the von Mises stress at a point. The verdict requires a minimum of 3.0 for 6061-T6 aluminium and 2.5 for AZ80A-T6 magnesium. |
| Signed numerical summary | The verified values of a result that LoudGears stores in the cloud: verdict, extremes, residual, and hashes. |
| IGES | An older CAD exchange format (.igs, .iges); ForgeNode converts it to a solid before the analysis. |
| Parasolid X_T | The text export of the Parasolid modelling kernel (.x_t, .xt); ForgeNode rebuilds it as an exact solid before the analysis. |
| STEP | A standard CAD exchange format (.step, .stp). |
| Tet10 | A 10-node tetrahedral finite element, used for the LoudGears analysis mesh. |
| Verdict | FEA PASSED, FEA FAILED, or FEA review required, decided by the minimum safety factor. |
| Von Mises stress (VM) | A single equivalent stress value that combines all stress components at a point, in MPa. |
