AFT Impulse’s iterative steady-state solver takes initial guesses (also called initial conditions) and applies the principles of mass and momentum balance to improve the guesses. This is called iteration. It continues to refine the solutions until agreement with the governing equations is obtained.

After a converged steady-state answer is obtained, you can choose to take these results and use them as the initial guesses for a subsequent run. This causes much faster convergence in subsequent steady-state runs because you are starting the solver at or very close to the actual solution.

Note: This will not increase the speed of the transient solution progress.

This feature is called Transfer Results to Initial Guess, and it is on the Output window, Edit menu and toolbar.
