The in-app guidance depends on the case:
- Mach < 0.3, density variation negligible.
- See the Create Simulation dialog for the full description.

Problems reported against this step
Section titled “Problems reported against this step”The application checks these before a run and reports them in the Problems tab against this step.
| Severity | Message |
|---|---|
| error | … has no steady form. … integrates in time; set Time dependency to Transient. |
| error | A two-phase case needs gravity. Without it there is nothing to separate the phases and the interface will not settle. |
| error | … has no turbulence model, so it will not read k, omega or nut. Set the turbulence model to Laminar, or choose a solver that has one. |
| error | … has no steady form. Set the time dependency to Transient. |
| error | … has no transient form. Set the time dependency to Steady-state. |
| warning | … needs …, which this app does not write. Add it to the case directory before running. |
| error | … is not part of the … tier. The case is safe and nothing has been lost - choosing another analysis type, or upgrading, will let it run. |
| warn | Gravity is off for a buoyancy-sensitive analysis type. |
… marks a value the application computes at run time, so the source carries no fixed text for it.
