With the parameters and options in this panel you will be able to crop the Hybrido mesh, remove unwanted parts, and extend the mesh to create the impression of a huge ocean surface. Changes are added automatically and there is live optional feedback in the viewport: if the interactive meshing mode is disabled please go the the "Mesh" shelf and click on the "Mesh interactive" button. In the first step, you have to go the desired frame and build a single mesh with

or the appropriate button in the "Mesh" shelf. Now, all changes within the "Boundaries" panel will be applied automatically and you do not have to rebuild the mesh manually. Once you are finished with your adjustments, simply recreate the mesh again to bake the settings to the current mesh. Finally, you can mesh the entire sequence. The parameters from the "Displacement", "Filters", and "Optimization" panels also support interactive meshing. For more information, please click here.
Open boundaries
When you take a look at the Hybrido domain's viewport representation you will see a square with four boxes – here only the square is interesting: it represents the projection plane for the fluid's displacement and image export (displacement, vorticity, velocity). When “Open boundaries” is set to “Yes”, the mesh polygons in the outer areas of the projection plane will be cut away. The plane's height also plays an important role, because polygons below the projection plane will be removed as well. Please also bear in mind that the plane's size is responsible for the displacement's scale.

This parameter describes the area where the core fluid surface is smoothed and is indicated by a dashed square. The bandwidth is measured from the fluid's border to its centre (outside → inside) and given in metres [m]. A value of 0, represents the fluid's border and disables the smoothing effect. The greater the value, the larger the smoothing area.
@ Fall Off Offset
By default, the smoothing process starts at the core fluid mesh's borders, but sometimes it is necessary to move this border and this is exactly what “@ Fall Off Offset” does. With values greater than 0, the core fluid part will shrink and the flat area (which can be seen as the connection between the extension and the main mesh) becomes larger.
