Objects also have the possibility to interact with grid fluids, but the number of settings is limited. The reason is that grid fluids are used as the core of fluid, while detailed interactions are created with standard emitters. In many cases, objects are used to push the fluid along a certain direction to create breaking waves. For all these applications a large set of parameters is not required.
Grid friction
...
Sometimes the interaction between grid fluids and objects might be too weak, so that the object hardly creates any visible turbulence or waves. With this parameter it is now possible to amplify the object's influence on the grid fluid and create more interactions and surrounding waves.
Mapped Parameters
You have already read that many parameters can be represented with image maps – here is some additional information. Image maps create areas of different influence, based on the colours of a bitmap or texture. The adjustments are made from a separate window, providing all relevant parameters and switches to make use of this feature. An additional function is that you are even able to load image sequences for animated parameters. Dark areas indicate zones with low values, while white represents the maximum.
