Hi Yu - If you are interested in sloshing and simulating that in Chrono, see this contribution: https://www.sae.org/publications/technical-papers/content/2018-01-1110/ It’s not simple, but it can be done. You need to have knowledge of CFD, not a stroll in the park. Alternatively, you can use DualSPHysics, that is interfaced to Chrono and is strong on the CFD side of things – see https://dual.sphysics.org/ . Good luck! Dan

I know it seems odd to solve an 1D fuild system in multi-body solver, however technically speaking, is it possible that I could rebuild this 1D fluid DAE system using ChronoEngine? If so, which Chrono module(s) or built-in solver(s) should I use? Thank you a lot in advance! best, Yu -- You received this message because you are subscribed to the Google Groups "ProjectChrono" group.
