[Description:]
|
|
|
|
The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The viscForce model calculates the particle based viscous force, -(grad(tau)) * Vparticle (see Zhou et al. (2010): "Discrete particle simulation of particle-fluid flow: model formulations and their applicability", JFM).
