SPH particle mass calculation

Hello,

I am generating a SPH mesh in HyperMesh. I set the pitch distance to 0.01 and the density to the value of the material I am using. The particle distribution I am using is simple cubic. Therefore, according to

https://2021.help.altair.com/2021.2/hwsolvers/rad/topics/solvers/rad/theory_sph_cell_distribution_r.htm

the mass of the particles should be automatically calculated as m_p = pitch^3 * density. However, the mass displayed in the SPH property that is created after the SPH generation is almost 1.75 times larger than the one expected by the formula above. Any suggestion on this?

Thank you in advance!
