To start the analysis, choose Start Analysis from the Analysis menu or toolbar. Hydromax will step through the parameter ranges specified, floating the hull to equilibrium conditions where required. Hydromax will redraw the contents of the windows to display the current hull position for each iteration.

Calculations may be interrupted at any time by selecting Stop Analysis from the Analysis menu or toolbar.

If you have stopped the analysis, you can resume calculation by selecting Resume Analysis from the Analysis Menu or toolbar.

There may be a slight time delay on all of these operations while the current cycle is finished.

You can also switch application by clicking in the window of any background program. Hydromax will continue to calculate in the background although its speed will be reduced. The drawing of the vessel at each step of the analysis can be quite time consuming. If you are not interested in seeing the progress of the analysis, switch to a table window and maximise it to speed up the analysis. Should the analysis take longer than about 45 seconds, Hydromax will flash and beep to indicate that the analysis has been completed.

The start, pause and resume functions are also available in the Analysis toolbar:
