I was runing some simulation with one macro pore in the structure and at the stage,some of the particles around this pore broken all of its contacts, so they basically floating around in side the pore area.
When I use VTK export the contact network, I find out that these 'free particles' are actually not free in a sense that they created hard contact with other particles but in a wierd sense, it seems to me that they are not touching but still the contact are established. (their distance is larger than (r1+r2)). see Figures.
Here my assumption that it seems to me the distance factor is larger than 1?
I checked the demfield the value is one but still I have strange behavior. Is there someway to prevent it from happening? I am thinking of letting particles with zero cohesive contact to disappear
S.dem.par.disappear(s.id, mask = 'somevalue')
