external force on floatings

Hello,

I want to impose external force on floating objects and the force changes over time. I don't know if it is possible in DualSPHysics and how to do it.

Thank you very much!

  • if you impose external force then floating body will not be a fluid-driven object....?
    what exactly do you want to simulate?
  • I have the same problem. I just want to simulate a boat in water driving by external forces that I impose on it and see how it will act. I can't just give an acceleration because it won't change during the simulation. In fact force and moment caused by water particles change.
    I am trying to modify the code and find it too difficult for me. I want to ask if I can treat the floating particles like water particles, using "forces.csv" to realize my request.
    And if there are better methods?
  • We have been working on that, and we are now implementing imposed linear or angular velocities to a floating body so the final motion will follow the equations for rigid bodies, but some linear or angular component follows the imposed motion or rotation
