Is there a way to apply a force to an individual particle?

I have particles bonded in the shape of a beam, and I want to apply force to specific particles so that the entire beam experiences deformation because of that force. Currently, in the Creator section, I only see the option to add geometry and assign motion to it.

But what if I want to impose motion/force directly on a particular particle?

Hi,

The best way to set a Motion type boundary is via the rigid link functionality:

https://help.altair.com/edem/topics/creator_tree_geometries/rigid_link_condition_t.htm

You can connect the end particles to a geometry and move that, the particles in contact will move as if rigidly connected to that specific geometry which you can control.

Hi Stephan,

Posting my old reply

""I think this feature isn't available in the 2022 version. Also this isn't what I want. When I specify force on a geometry, the particles will follow it and interaction of geometry with other particles in the domain doesn't change the motion of the geometry.

Can you guide me to write the custom API that can help me specify forces on intended particles.""

It is a kind request to please upload a short tutorial or guide me on how to apply motion and force directly to specific particles based on their IDs using the API.

I have been stuck with this issue for a long time and have repeatedly posted in the community but have not received any help. Please help.
