Formula to roughly estimate number of particles
There is a limit to particle numbers for DualSPH CPU version. So i thought to keep a condition statement to calculate the number of particles for given particle distance and volume and compare it with the maximum allowable number of particles. So, I was curious if there is any rough way to estimate the number of particles and whats the maximum limit for number of particles in CPU DualSPH ?

The same issue can be also raised in mesh-based codes to determine the cell size...
What we use for wave propagation is 8-10 particles in one wave height, so that H/dp=8-10 (Altomare et al., 2017)
