Randomization of particle release and collision count on geometry walls

Kiran Purushothama Keshavan

Hello,

Can we count the number of particles hitting a boundary or a wall? If yes can you please refer me to a particular source to look at?
Is it possible to generate same set of random injections on EDEM from the factory? I want my simulations as repeatable as possible.

 

Thanks,
Kiran

Hi Kiran,

You can use the dynamic block factory to record a set of particle and then repeat the placement of these.  The dynamic block factory is covered in the e-learning 'EDEM Creator: Material Block Dynamic' lesson:

We can count contacts with particles and walls but these are instantaneous contacts so it depends on your save interval as to how good a resolution of results you need for this.  There are also API options for this such as:

This case counts and removes particles but the code could be modified.

 

Regards

Stephen
