Is it possible to see overlap for a specific agglomerate?

Hello every one,
I calculate the gyration radius for all of the agglomerates in my system(in EDEMpy).
But there is one thing that I don't understand;

I have a lot of agglomerates that contain 2 primary particles.  I thought that the gyration radius would be the same for all of them, however it is not.
Some of them have gyration radius that are bigger than dp, while others are smaller. (dp stands for diameter of primary particles and there is no particle size distribution for primary particles)
The only think that I think is to know the value of overlap for all of agglomerates. 
I only saw the overlap vs. time or distance plot (total or average).

Is it possible to see the overlap for a specific agglomerates?

It would be appreciated if you have any other suggestion for this problem.

Kind Regards,
Fatemeh

    Hi Fatemeh,

     

    I'm assuming that the 2 primary particles that make the agglomerate must be in contact with each other. If that's the case you can check the overlap with the command deck.timestep[tstep].contact.surfSurf.getNormalOverlap() / deck.timestep[tstep].contact.surfSurf.getTangentialOverlap()

     

    Best regards,
