Question about Momentum Equation
Hi everyone
I have a question about the press gradient term in momentum equation, that is used in the code of DualSPHysics_V4.0
It's said, in the DualSPHysics_V4.0_GUIDE, the press gradient is written how:

but, in this same text, it's said that this is according to Monaghan 1992. I searched in this paper and I found the next discretization:
https://drive.google.com/file/d/0BxdyfmapfgNQVGFQWDhKczZ3d1k/view?usp=sharing
which is not the same that is shown in the GUIDE file. I just want to know which of them is really use in the DualSPHysics code, and maybe why?. If it's possible, I wish someone can tell me in which file and where, can I see the implementation of this equation and be able to change it.
Regards
