EDEM API factory minimum scale/diameter

Hi,

I have a code creating particles varying in size and am currently using the scale function in "createParticle" under the EDEM factory API to do so. However, I realize that some of my smaller particles (scale < 1e-3, diameter < 1e-3mm) are not being created. However, when I increase their scale, they are able to be successfully created.

As such, may I find out if there is a minimum scale/diameter for a particle to be created using the EDEM API factory? And if so, what is the minimum value?

Regards,

Megan

Hi Megan,

There is no limit to the particle size you can create with an API factory.

One possible explanation for what you are observing is that small ones are created but accelerate very rapidly and leave the domain due to their small mass and some initial overlap with other particles.

It might be worth checking the solver report to see if any particles are leaving the domain or "failing"on generation.

Best regards,

Stefan
