For this tutorial, we assume that you have a simulation running, and it is properly using the high-performance GPU on your system.
Close the “Start Here” Panel, and open the “Modify Visualization” Panel:
First, click on the “Colorbar Choices.” You will see that there are a number of different colormaps. For example, change the colormap to “Turbo”:
The colorbar is displayed at the bottom of the animation – scroll down to see it. To change the limits of the color axis, change the Color Axis Values. For example, change the limits to map from -2 to 4:
If you do not want to see the breaking foam in the visualization, choose “No Foam or Tracer” in the transport overlay dropdown. You can change the topography overlay and turn off the logos here as well:
Back to the top of the panel, you see there are a large number of “Property to Plot” options:
These are mostly self-explanatory, and can be used to visualize the various state and derivative properties solved by the Boussinesq equations. Note that the wave height surfaces are found using a running sum to constantly update the free surface variance at every location, and that variance is used to determine the wave height.
Finally, at the bottom of this panel, there are two main “View Modes.” The default mode is “Design”, for when the user wants to modify the bathymetry or add design components interactively (more on that in Tutorial 3). The “Explorer” mode allows the user to zoom-in (using the scroll wheel on a mouse or pinching motions on a touch pad / tablet), move the canvas (hold left click on a mouse, and then move the mouse, or swipe on a tablet), and rotate the canvas (hold right click on a mouse, and then move the mouse). By clicking “View Simulation in Full Screen” the animation will transition to full screen in Explorer mode, and the Explorer mouse options will work, allowing the user to examine different parts of the simulation in detail:
