Yu, Currently, it’s not possible to append a generic dynamic system to be solved simultaneously with the underlying Chrono dynamics. You will need to adopt a co-simulation approach.
--Radu From: [email protected] <[email protected]> On Behalf Of Guan Yu Sent: Tuesday, June 7, 2022 12:43 PM To: ProjectChrono <[email protected]> Subject: [chrono] Discrete/Continuous hybrid DAE system Hi there, I just started learning ProjectChrono and I am trying to build a rocket launch simulation that contains multiple sub-systems such as a liquid rocket engine system, control system, etc. I believe that ProjectChrono will perfectly get the multi-body part done, but I have the following question: I had successfully modeled the engine system as a 1D fluid system using OpenModelica(a Modelica software that could solve custom-build DAE system), the model ends up to be a discrete/continuous hybrid DAE system (has around 500 constrain equations that solving 500 variables in which there might be 50 state variables) that solved by DASSL solver. 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.
