multiphere particles

Submitted by ranius on Mon, 12/22/2014 - 11:55

Hello everyone,

I'm trying to pack rashig rings to create a packed bed reactor.
I don't know from where I have to start. I have an STL of the ring, I think I have to create a clump of that shape and then use the multisphere particle template. Is it right?
I'm not able to create the dump file from the STL, can anyone help me?

Any hint or suggestion is very helpful

Thanks
