Menu: Window->Several results...
With this window user can select whether to view the results one by one, as usual, or to view some results visualization types at once, e.g. a contour fill of pressure and velocity vectors at the same time. From this window you can also delete the undesired results visualizations. After selecting the desired behaviour, press the Apply button.
