particles in front of wall

Submitted by naren on Wed, 12/03/2014 - 06:41

Hi All,

I have a stl geometry in my simulation. I want to attach (fix) one layer of spherical particles on the surface of this geometry.
How can i achieve it?

Any help will be much appreciated.

Thanks,

Narendra

Hi Narendra,

you can do it like this: Make the geometry very cohesive, add particles to the simulation,then move the geometry away, and save the particles via write_restart

Hi Narendra,

every wall has a "type" associated to it. All the pairwise properties, also e.g. cohesionEnergyDensity, define a matrix of interactions.
E.g if particles are type 1 and wall is type 2, you could define the cohesionEnergyDensity for 1-2 as a high value
