Re: [Question #698303]: packing porosity for heat capacity scaling according to desired porosity of material

 

Question #698303 on Yade changed:
https://answers.launchpad.net/yade/+question/698303

Robert Caulk proposed the following answer:
I don’t see the difference between scaling from 0.47 and 0.15 down to
0.015. Either way you are scaling around an order of magnitude.

That said, from a DEM perspective i am surprised your porosity is 0.47 for
a random dense packing that is compressed. I have no way of checking if you
are looking at porosity correctly because you did not share a script.

Cheers,

Robert
