Surface Force should work with other particles as vertices

[MatthiasM]

However, for upresing simulations, there is already a dedicated operator: particle force. You input a separate flow and it will advect your current flow with the linear/angular velocities of the input flow based on a set radius. It was specifically designed to do upresing.

yes thats exactly what i am doing but for more detailed simulations the upresing from interpolated proximity velocitys alone tends to become blurry by the nature of its functionality so i want to slightly pull the particles towards the reference particles at the same time. Also "point force" only works in a self related way and not for negative/attracting values like the surface operator right? I imagine attracting and repelling my particles towards/away from particles of another flow
