Hello, I am working with the lagrangian particle tracking solver, DPMFoam, in openfoam 2.3.0
Does any one know any what does each of the following parameters (in kinematicCloudProperties file) exactly mean:

        pairSpringSliderDashpotCoeffs
        {
            alpha               0.02;
            b                     1.5;
            cohesionEnergyDensity 0;
        };

and:

       wallSpringSliderDashpotCoeffs
        {
	    distance	    0.002;
        };

and how can i define a rigid particle (no elasticity)?
and what is a reference for defining and explaining the theory of Spring-Slider-Dashpot collision which has been used in openFoam/kinematicCloud class?
