Is force field able to affect particle/deformable body?

I have a question about force field.
I wanted to use the force field in a simulation of a liquid vortex and a deformable body, but the force field does not work on anything but rigid bodies. Is there any way to get it to work?

Hi @himajin - There is a force field document here: Force Fields — Omniverse Extensions latest documentation

I have assigned the question to the PIC, who can answer further here.

Correct, the force fields extension currently works only with rigid bodies. There is unfortunately no workaround to get it working with with particles/deformable bodies. We are aware of this limitation and the work to have this working is on the table just not yet productized. Sorry.

Hi, I have a project and also need to use the force fields to get it working with particles/deformable bodies. So I want to know if you have any plans to launch this feature and when

We don’t have a timeline for this, but as a workaround you can implement the forcefield yourself and apply forces to the particles and deformables via velocity deltas on the particles or deformable vertices.

Could you tell how to apply velocity deltas on the particles? I only know how to read the particles’ positions by using the UsdGeom.Points.GetPointsAttr().

There is also a velocity attribute: Universal Scene Description: UsdGeomPointBased Class Reference
