In the CohFrictMat material, the introduction of the parameters normalCohesion and shearCohesion is so simple that I don't know the detailed meaning of them. Are they coefficients of attractive force? What's the relationship between them and the distance? Are they a part of interaction model between particles? Should they be recorded into the DEM Background in the doc.?
