How to measure the area of overlap between particles and geometry in EDEM

Hi All,

In the EDEM simulation, the geometry presses the granular layer and if I want to normalise the data, the area of the overlap between the granular layer and the geometry needs to be obtained. Therefore, how to measure the area of overlap between the geometry and the particles?

Many thanks in advance for your help!

Regards,

Chao

    Hi,

    There's not an automated way to get this but it shouldn't be too difficult to obtain this within the API. You can get access to the contact point, particle sphere centres and particle sphere radii within a contact model. With a bit of trigonometry you can then calculate the distance between the contact point and the edge of the particle, which you can then use to calculate the area of a single contact.

    Cheers,
