Define how the analysis runs with the Control tab of the Solve dialog.
Set the Solution Mode to Steady State or Transient.
If Transient, set the Transient Parameters (time step size, etc.)
Set the Save Intervals for Results and/or Summary
Select the Solver Computer (the local computer is the default).
If continuing an analysis, select the Iteration or Time Step to Continue From.
Enter the number of Iterations to Run (or Time Steps to Run)
The Solution control tools provide control over how quickly the calculation progresses to ensure a robust, converged solution. In addition to the manual controls, Autodesk® CFD contains a great deal of Analysis Intelligence which automatically controls the rate of convergence as well as determines when the analysis is converged (no longer changing).
Optional: select additional Result Quantities.
