Solution Types and Convergence

Each finished run is labelled with how its solution ended. The label is shown in the Runs tab, the coefficients table, the Flow tab and the report.

Label	Meaning
Converged	The full convergence check passed: the loads are stationary, and the residuals, continuity and turbulence-bounding criteria are met.
Steady loads	The loads settled within the tolerance of the check, while residual or bounding criteria still failed. The loads are usable; this is common on fine, wall-resolved meshes.
Unsteady · mean	The flow is unsteady, for example vortex shedding, and the mean of the loads settled. The value is a mean, not a time-accurate result.
Not settled	The iteration limit was reached before the loads settled. Treat the values with care.

The loads of a run are averaged over its last iterations. The Flow tab shows the convergence plot of CL and CD with the averaging window, for example Loads averaged over iterations 333–664.

Run stages

While a run is in progress, its stage is shown:

Queued	Waiting for an earlier run.
Preparing	The case is being written.
Meshing	The aircraft is being meshed at its attitude.
Initialising	The flow field is being initialised.
Solving	The solver is iterating.
Checking	The result is being checked and the loads extracted.
Complete	The run is finished.
