Hello. All that you are intersted in seems to be stored
-  either in the "interactionGeometry"  (which could be of 
SphereContactGeometry type for example, see : 
pkg/dem/DataClass/InteractionGeometry/SphereContactGeometry.hpp)
- or in the "interactionPhysics"(which could be of 
"ElasticContactInteraction" type, see : 
pkg/dem/DataClass/InteractionPhysics/ElasticContactInteraction.hpp)
So what you have to do is to create your own Engine which will loop over 
all the interactions (like that :
   InteractionContainer::iterator ii    = 
ncb->transientInteractions->begin();
   InteractionContainer::iterator iiEnd = 
ncb->transientInteractions->end();
   for(  ; ii!=iiEnd ; ++ii ) {
)
and will store in output files the things you need (see for example all 
Engines "...Recorder")
