How can I export the contact radius from the EDEM API into a file?

Question

In the EDEM API, I can access the contact radius and use it in my calculations.

However, I would like to export this contact radius data as a separate file.

My questions are:

* Is it possible to extract and save the contact radius (or total contact radius) as an output dataset?
* If so, how can I convert this data into an external file (e.g., CSV, TXT)?

For example, can this be done using the EDEM API, custom properties, or a scripting method?

I would appreciate any guidance on how to obtain the contact radius values and store them as a file.

Thank you!

Hi,

The contact radius should be consistent with the size of the particle.  So if you have set a contact radius on a particle in the EDEM creator, this shouldn't change for the particles in the simulation.

The best way then would be to export particle diameter from the Analyst, this doesn't give you the contact radius directly, but if you ahve a size distribution, you can compare the particle diameter to the diameter of the particle in the creator and this scale value will also be the scale of the contact radius,.

Hi,

You can get the Normal Overlap by exporting the Contact information, would this be sufficient?

On the contact radius yes, its remains constant, same as the physical radius is constant unless additional custom physics models are included to scale the particles during run time, in which case the contact radius would also be scaled.
