DDT from a numerical point of view

hesamhesam
in DualSPHysics v5.0

greetings everyone!

According to the numerical calculations of SPH, what term is created in the continuity equation that we have to use DDT?

I would be grateful if you could introduce a useful article to explain my ambiguity!

Regards
