How can I calculate collision efficiency?

Fatemeh Hosseini_22198

Hello everybody,
I must determine collision efficiency.(Number of collisions that create aggregates)
I created a Python code that uses the distance between particles to determine the number of agglomerates and the primary particles in each aggregate.
The collision efficiency calculation process is more difficult than the computation for agglomerates.
Based on their shapes, two aggregates with the same number of particles may have different collision efficiencies. So I am not sure how to counts the number of successful collision. 
Could  you guide me in this field?

Hi Fatemeh,

For collisions what kind of resolution of data do you need to have, are you running the simulation with 'track collisions' in the EDEM Analyst?  

It maybe something more suitable to calculating during processing in the API rather than post-processing with the python interface.  There is a collision tracking API for Energy loss here which you could review:
