[Question #669519]: Drag force

 

New question #669519 on Yade:
https://answers.launchpad.net/yade/+question/669519

Hello,

I'm new in Yade and I need to simulate the effect of an air flow inside a tube.
I initially modeled it by imposing a given velocity to the particles but i would like to improve my work.

I read about the dragEngine that simulates the drag effect on particles that move at a specific velocity. I thought that I should need to specify the air flow velocity in the dragEngine.
In this way I would obtain a drag force that essentially would represent my air flow. Unfortunately i observed that this option has not been already developed. 

Before than apply it manually I would like to ask you if there is any alternative function able to solve my problem.
Thank you so much.

Best regards,

Francesco
