This is the place for the mesh’s fundamental settings. They influence the way the polygons are created around the particle cloud directly and determine the mesh's quality.
Build
This option tells RealFlow whether the mesh should be generated during the simulation process or not. We do not recommend setting it to “No”, because meshing should always be a post-process. There are so many settings that it would actually be impossible to create a convincing mesh on the fly simultaneously with the particle simulation.
Weight normalization
A normalization step produces better results in areas where particles are clustering. When this option is enabled the mesh polygons will match the underlying particle cloud much better, but at the cost of increasing creation times. By default, this parameter is set to “No” in order to speed up the meshing process.

If you are not happy with the automatically defined radius, set “Auto particle radius” to “No” and enter a value of your choice here. Please bear in mind that very large values can drastically increase mesh creation time.
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.
