What is the physical significance of scaling factor used while coupling? For ex- if I increase or decrease the particle radius by 100 times then, what value should I put in scaling factor tab?
Hi,
I can't find the post I wrote on this a few years ago, looks like it'll need recreating, but if your 'real' particles have a diameter of 2.5mm, and you take a coarse graining approach to simulate your particles at 25mm, you would enter a scaling factor of 10. This factor is required to ensure the forces on the scaled-up particles are consistent with the scenario they are aiming to model, i.e. in my example the 25mm particles should act like a clump of 2.5 mm particles.
Cheers,
Richard
