how to detect particles inside contact radius?
Hello
I am trying to use Hertz-Mindlin API to implement screening distance. But unfortunately I am able to activate the API only when physical contact happens.
Can you please tell me how to get away from this?
I have selected this in the factory.
and In API
If I activate line 205 and 206 it does not get activated when there is contact overlap (in the absence of physical overlap)
please tell me if I'm doing anything wrong

Yes I am positive I have the particles inside contact radius. Not sure why it's still not detecting it. Even in debug mode the contact model only gets activated when the particles come in physical contact.
Never mind this was my confusion
I was under the impression that
The condition on line 203 is for actual physical overlap.
Your terminology on EDEM is confusing; as a user, I would think
contact.normalPhysicalOverlap <= 0.0 -> This is a condition for when the particles physically overlap
and
contact.normalContactOverlap >= 0.0 -> this is the condition when the contact radius overlaps
but its the other way around
contact.normalPhysicalOverlap <= 0.0 -> This is a condition for when the contact radius overlap
contact.normalContactOverlap >= 0.0 -> this is the condition when the physical radius of the particles overlaps
I can stop the program when the contact radius starts overlapping
Hi Shyam,
The code looks OK to me. Do you definitely have particles with contact radii set in the simulation? Have you tried debugging to see what happens when you hit that IF statement.
