[Description:]
|
|
|
|
The force model performs the calculation of forces (e.g. fluid-particle
|
|
interaction forces) acting on each DEM particle. The {gradPForce} model is a
|
|
model that calculates the particle based pressure gradient force -(grad(p)) *
|
|
Vparticle (see Zhou et al. (2010): "Discrete particle simulation of
|
|
particle-fluid flow: model formulations and their applicability", J. Fluid Mech.).
