Interaction with External Field

Submitted by abhishek on Tue, 08/21/2012 - 21:27

Hello Liggghts Users,

I like to use DEM method for charged particles such that they can interact with external electromagnetic field. So I have following questions :

1) Is it possible to define external force field for example Electrostatic force as an analytical expression ?

2) Is it possible to use external field a numerical solution as calculated from other FEM package i.e. field values over a grid of points and use the interpolated field etc. ?

Sincerely,

Abhishek

Hi Abhishek,

for 1) you can use fix efield, 2) would require you to either extend fix efield or write some other offline coupling
