Hi again Rob, sorry for the delay in my answer. I have been diving into the basis of the Euler-Lagrange model. The conservation equations referred to the particles (Lagragian framework) do not include terms with their derivative with respect to the position (nabla operator), they only include terms with their derivative with respect to time. When trying to work in steady state, the value of these last terms will be 0. I have been checking other works that go over Euler-Lagrange, and in some of them it is specified that they work with steady state flow (no specification is made about the particles). My question is whether I can work with particles in steady state. Is there some way to do so? If I want to consider the mass transfer, do I have to simulate in transient state for the particles? Thank you in advance.
