Can I add force wind to the smoke so that the smoke follows a trajectory like in the picture?
Is it possible to make the smoke start from the surface of the 3D model?
To have smoke emit from your 3D model, set the type on the Nvidia Flow Emitter COMP to Shape SOP and then reference the SOP on the Shape OP parameter.
Regarding your force question: I’m not sure if it’s possible to achieve that specific effect but you may be able to achieve something close by playing around with the gravity and vorticity parameters on the Nvidia Flow TOP. And by the way, the Force COMP is not used as a part of Nvidia Flow simulations. It’s used only with Nvidia Flex or Bullet simulations.
