How to calibrate when simulating scaled particles using EDEM-Fluent coupling

Hi there

I'm simulating a case with very small particles, but it will cost too much computation source and time. I've learned that it can be solved by scaling up the particles. It seems like the scaled-up particles should be correctly calibrated so that they will behave the same as the smaller ones. But what should I do to calibrate them in EDEM and Fluent? For example, I'm simulating sand particles suspended in the air with a diameter of 0.1 mm. If I scale up the particle diameter to 10 mm, should I adjust the density in EDEM to make the two particles have the same mass? Any other steps should be taken?

I appreciate your response.
