How to simulate smoke in Flow under the influence of a forcefield wind

I’ve tried simulating smoke in Flow and interacting with objects (e.g., using Convex Decomposition), and I’ve also experimented with the wind forcefield extension.
However, I’ve tried many ways but still can’t get the forcefield wind to affect the flow of smoke.
Does anyone have experience with this? Thanks.

Let me see if I can get you some help. Thanks.

The wind forcefield extension does not interact with the Flow extension.

The way we have done wind effects in the past is to use a large Flow box emitter with allocationScale = 0.0 and a low couple rate velocity (like 0.5, all other channels couple rate = 0.0). The USD velocity attribute on the emitter can then be animated anyway you like, Python, OmniGraph, USD time samples.

Thank you for your explanation. Based on your response, it seems I’ll need to construct a user interface using OmniGraph or Kit to function as a wind controller. I’ll explore this further. Thanks for your help.
