Hi Shipeng, The video you found was not simulated using DEM, but using SPH. The SPH method was implemented in Chrono as a fluid dynamics solver and has the capability to interact with rigid/flexible multibody systems (e.g. a robot). I think you can follow the steps in the previous email. But one more thing you need to confirm is: do you want to simulate the dynamics of a robot that interacts with different fluids at the same time? If not, things should be straightforward, you just need to set a viscosity and run a simulation then change the viscosity and run another one. If yes, that should be a multiphase problem which will be a little bit complicated. We have the capability to simulate a multiphase problem, but that's still under development and should be in the public repo of Chrono soon.
Thank you, Wei On Saturday, May 21, 2022 at 10:01:54 PM UTC-5 [email protected] wrote: > Hi, > > I am a freshman to project chrono~ I found the demo video on Vimeo. > https://vimeo.com/31809642 > I want to simulate the robot's motion in Fluids with different > viscosities.
