Reference to Tsuji(1992) for SpringSliderDashpot
A while ago, I was not familiar with DEM and the literature on it. I started using DPMFoam and I wanted to know how the collisions worked. Then I had a hard time figuring out the spring slider dash-pot collision model in the lagrangian-intermediate library.
Eventually I found that it is the implementation of the Tsuji(1992) paper. Would it be possible to make a reference to this paper in the following models: WallSpringSliderDashpot, WallLocalSpringSliderDashpot and PairSpringSliderDashpot?
For clarity I've included the paperTjuji_1992.pdf
