Transfer Results to Initial Guesses

AFT Fathom’s iterative Solver (the part of AFT Fathom that applies the governing incompressible flow equations to obtain a solution to the pipe system) 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. This causes much faster convergence in subsequent runs because you are starting the solver at or very close to the actual solution.

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