calculating electrical force in a 2d model

Please login with a confirmed email address before reporting spam

Hi,

I am tring to simulate an electrostatic force initiated on a drop.
i am simulating the drop with a 2D geometry and i cant understand the force result. i am simulating with the electrostatic physic.

There is to things that i request your help:

1. can i get the force field (from the force calculation node) as a function of place (and not as a scalar) ?
2. what does the force result mean in a 2d simulation.


Thanks in advanced for your help !

ofir.

Hi

I suppose you mean that you get a force density = pressure N/m^2, so to get the total force you need to integrate it over the boundary where the force applies. Check the doc about the coupling integrations or the definition Integration nodes, or the derived values integration ...

Good luck
