Transfer Results to Initial Guesses
AFT Arrow's iterative Solver takes initial guesses (also called initial conditions) and applies the principles of mass, momentum and energy 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 answer is obtained, you can choose to take these results and use them as the initial guesses for a subsequent run. Using the converged results as initial guesses often gives faster convergence in subsequent runs because you are starting the Solver at or very close to the actual solution.
