This is the place for the mesh’s fundamental settings. They directly influence the way the polygons are created around the particle cloud.
Weight normalization
When enabled you will see better results in areas where particles are clustering, because the mesh polygons will match the underlying particle cloud better. Anyway, this option is not a replacement for a sufficient amount of fluid particles.
Auto polygon size
With “Yes”, RealFlow automatically adjusts the polygon size to get the best balance between quality and number of faces.
@ polygon size
Smaller values take longer to calculate, lead to larger mesh files, but also more detail. A good starting value is the suggested value.
Auto particle radius
With “Yes”, RealFlow automatically adjusts the radius to get the best balance between quality and meshing speed.
@ particle radius
The mesh engine draws a sphere around every particle and extracts the mesh's surface from this structure. The radius of these spheres is defined here and the suggested value is a good starting point. Meshes will be created very fast when "@ polygon size" and "@ particle radius" are equal.
