Smaller values take longer to calculate, lead to larger mesh files, but also more detail. A good starting value is around 0.02. The corresponding → “Radius” value can be calculated this way: Radius = Polygon size * 1.7. Meshes will be created very fast when "@ polygon size" and "@ particle radius" are equal.the suggested value.
Auto particle radius
With “Yes”, RealFlow automatically adjusts the radius to get the best balance between quality and meshing speed.

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 . A and the suggested value is a good starting value is: Radius = Polygon size * 1.7. Meshes point. Meshes will be created very fast when "@ polygon size" and "@ particle radius" are equal.
