[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" ,JFM).
