Software Convergence

The new version of the software that is under development will inform the user about the convergence of the solution algorithm. It was mentioned in a previous blog post that the software employs an iterative solution scheme. The image below shows how much the solution variables changes from one iteration to the next. The algorithm will stop when the tolerances of all the solution variables are below pre-defined values. These tolerance levels are also indicated on the graphs. It is evident that the water outlet temperature, or Two, was the last variable to reach the predefined tolerance level. The values on the y-axis are shown on a log scale.

Convergance Tolerance

The next image shows how the values of the solution variables converge to the final values.
