# 1. Load the size-relevant particle data for the first time step
Bounds_t0, Diameter_t0, Density_t0, Mass_t0, GlobalID_t0 = CG.data_sampling()
# 2. Calculate the particle size range
d43, d32 = CG.get_particle_size_statistics(Diameter_t0, Mass_t0)
# 3. Get the phases
CG.get_particle_phases(Diameter_t0, Density_t0, GlobalID_t0, 8)
# 4. Calculate the CG mesh spacing
CG.set_resolution(d43) # can input different number
# 5. Generate the CG mesh
CG.generate_grid()
# 6. Calculate the CG fields
