Status: Open => Needs information Jan Stránský requested more information: > - I want to calculate the same thing but when it is still loose pack(before being compress), can I just put the same calculation method into unload plate section? What is "the same thing"? Method should be the same, values (e.g. "top") not all. > Bulk mean both Sphere and Air OK, now I am lost :-) I would understand if spheres is bulk. Or spheres represent air bubbles and the complement is bulk. But bulk being "both Sphere and Air" sounds really unusually. Brainstorming: volume_packing ... volume of spheres new_volume_cylinder ... total volume new_bulk_volume = (new_volume_cylinder - volume_packing) new_bulk_volume is volume of void space So why is it called "bulk"? I think this is the source of the problem.. new_bulk_density = (density * volume_packing) / new_bulk_volume new_bulk_density = (mass of spheres) / (volume of void space) What is the meaning of such quantity? new_vma = (new_bulk_volume - volume_packing) * 100 What is VMA? "Voids in the Mineral Aggregate"? What is its proper definition? Why (volume of void space) - (volume of spheres)? Why * 100? new_air_void = ((new_bulk_volume -volume_packing)/new_bulk_volume)*100 void ratio? If so, it should be volume_void / volume_solid, i.e. using your variables: new_bulk_volume / volume_packing new_porosity = (new_volume_cylinder - volume_packing) / new_volume_cylinder seems OK Cheers Jan -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : yade-users@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
