external force on floatings

chengm

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!

Alex

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?

Alex

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
