Controls
No control on this panel carries a label that could be read from the source, so none is listed here. That is a limit of how this page is generated, not a statement that the panel is empty.
Problems reported against this step
The application checks these before a run and reports them in the Problems tab against this step.
| Severity | Message |
|---|---|
| warn | The body above is also free to move, and it is small relative to this mesh. A moving body needs more cells across it than a fixed one - a mesh-motion step that is large next to the cell size inverts a cell before the Courant limit can slow it down, and the run reaches a real nan rather than converging. Refine around the body, or lower accelerationRelaxation, before trusting a run that reaches End. |
| error | Cell zones and multi-region cases are not part of the … tier. Remove them, or upgrade. |
| error | The mesh moves, so the case cannot be solved steady-state - a steady solver never updates the mesh. Set the time dependency to Transient. |
| error | Overset is enabled, but there is no overset build of …. Remove the overset zone or choose an analysis type that has one. |
| warn | Overset and Body motion are both enabled. A mesh has one motion: constant/dynamicMeshDict writes the 6-DoF motion solver and Overset has no effect while it is on. Remove one of the two. |
… marks a value the application computes at run time, so the source carries no fixed text for it.
