[Description:]
|
|
|
|
The force model performs the calculation of forces (e.g. fluid-particle
|
|
interaction forces) acting on each DEM particle. The {DiFeliceDrag} model is a
|
|
model that calculates the particle based drag force following the correlation of
|
|
Di Felice (see Zhou et al. (2010), JFM).
