Each SPH element must have an effective mass. The effective mass of each SPH element is determined by entering either a material density of the material which fills the volume; or the total mass of the material in the filled volume, called the filled volume mass.

If entering a material density, the SPH mesher determines the effective mass for each SPH element from material density, volume to be filled with SPH elements, and number of SPH elements generated as follows:

 

If entering the filled volume mass, the SPH mesher calculates effective mass for each SPH element from filled volume mass, and number of SPH elements generated as follows:
