Hi Ivan,
I have the example you suggested working and was able to bring in a mesh to act as a prop on a motor. I am going to play around some more with DualSPHysics now. My goal is to be able to control the props in the simulation and see what that does to the the fluid and motion of the hull. My understanding is that you can setup the initials with the current chrono coupling but not set them in simulation? I guess that makes sense if it is a link? It seems that the chrono lib in the DualSPHysics is modified.. Any chance you know where I can get the source for that so I can better understand the coupling? Again any help or suggestions would be greatly appreciated.

In case you need something in depth about DualSPHysics, feel free to contact me.

I do have Irrlicht working with some of the other examples. Also a big thank you for offering to provide some help with the coupling of DualSPHysics and Chrono. I will take you up on that offer. I have spent a fair bit of time working on it from the DualSPHysics side of things but have been getting strange results. I didn’t see the source of Chrono that DualSPHysics is using, but there seems to be some modification of the library to make it work. If I were to guess, I would Imagine DualSPHysics is using links and not motors, but that is just a guess. I would like to add some real time controls of the motors. I was just overwriting the angular velocity of a boats prop which worked for about a second of simulation time and then the Prop would become instable. So now I am playing around with Project Chrono to better understand its workings and capabilities. I also noticed that DualSPHysics comes with its own SPH solver, FSI.. I don’t know if it is worth looking at that route as well. Thanks for your help. It is greatly appreciated. For now I’ll spend my afternoon looking through the example you provided. I have also been playing around with the demo_MCORE_motors example as well. With the example you sent I’ll try to replace a rotating rectangle with a prop and report back my results. Thanks again for your help. It is appreciated.

I know I have some work ahead of me. As a first step I am just trying to get a couple of motors working with props. I have spent signigicant time trying to get the working with DualSPHysics and am now working through how Chrono works. Can anyone point me to a simple example of how to import a mesh? I found this example online: https://urldefense.com/v3/__https://api.projectchrono.org/development/tutorial_pychrono_demo_mesh.html__;!!D9dNQwwGXtA!QbywaaeG0V_1TxapZwzkvu0Tq40k-aFkNAROV5GgGxYKQd09lKR0HmRZgEnG2CZrIWBnyewKCEZHWpHe6XBmL69Agjg$<https://urldefense.com/v3/__https:/api.projectchrono.org/development/tutorial_pychrono_demo_mesh.html__;!!D9dNQwwGXtA!QbywaaeG0V_1TxapZwzkvu0Tq40k-aFkNAROV5GgGxYKQd09lKR0HmRZgEnG2CZrIWBnyewKCEZHWpHe6XBmL69Agjg$> but that uses pychrono. I am currently using the C++ API. Then I compiled this tutorial: https://urldefense.com/v3/__https://api.projectchrono.org/tutorial_demo__f_e_a_cosimulate_load.html__;!!D9dNQwwGXtA!QbywaaeG0V_1TxapZwzkvu0Tq40k-aFkNAROV5GgGxYKQd09lKR0HmRZgEnG2CZrIWBnyewKCEZHWpHe6XBmPXV2RBc$<https://urldefense.com/v3/__https:/api.projectchrono.org/tutorial_demo__f_e_a_cosimulate_load.html__;!!D9dNQwwGXtA!QbywaaeG0V_1TxapZwzkvu0Tq40k-aFkNAROV5GgGxYKQd09lKR0HmRZgEnG2CZrIWBnyewKCEZHWpHe6XBmPXV2RBc$> which compiles fine but I am missing the rest of the files that go with the example so it doesn't run. I'll have a look through the git repo to see if I can find them, but at the same time if someone can point me to a nice simple example that would be great.
