SPS stress equation

Atefeh_FAtefeh_F
in DualSPHysics v4.4

Hello,

In the Dualsphysics formulation, I see the following formula for SPS stress tensor

compared to what I see in Dalrymple et (2006)

and in Shao and Gotoh (2005)

I got confused. which one is correct? all of them are cited in the Dualsphysics formulation. I think the k in the documentation should be replaced by Skk. Is there a typo in the formulation of Dualsphysics? if not, how we can explain the differences between the equations?

    It should be correct here:

    Domínguez JM, Fourtakas G, Altomare C, Canelas RB, Tafuni A, García-Feal O, Martínez-Estévez I, Mokos A, Vacondio R, Crespo AJC, Rogers BD, Stansby PK, Gómez-Gesteira M. 2021. DualSPHysics: from fluid dynamics to multiphysics problems. Computational Particle Mechanics. doi:10.1007/s40571-021-00404-2.

    Otherwise please let us know again
