Dear Foam users,

I am trying to make floating box simulation similar as indicated in this video: http://www.youtube.com/watch?v=bb9lhV6HgMQ

To do this, I used the interDyMFoam/floatingBox tutorial case for a sample. Since, I use the dynamic mesh utility first time, I could not decide which option I should use in dynamicMeshDict. I want box to move with the wave therefore, floatingbox tutorial dynamicMesh option is not fit to this. After searching, I found following linearMotion option:

dynamicFvMesh   solidBodyMotionFvMesh;

motionSolverLibs ( "libfvMotionSolvers.so" );

solidBodyMotionFvMeshCoeffs
{
    patches      floatingObject;
    
    solidBodyMotionFunction     linearMotion;
    linearMotionCoeffs
      {
         velocity (1 0 0);
      }
   }
    
}

Even the box is moving with this option, however the box looks fixed and not only box but also all domain is moving.

could someone tell me which dynamicMEsh option I should use to make similar simulation as indicated in the video.


Thank you.

Noone has any experience about this topic before?

Hi,

I think you refer to solidBodyMotionFvMesh option, which allows the whole mesh to be translated/rotated. dynamicMesh is well explained in the second link :
