DDT from a numerical point of view
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

Thank you for your guidance
Only the second article is available to me
