Hi everyone!

I want to connect a static mesh (a digital elevation model of a lake) and a dynamic mesh (the dam in front of the lake). I want to gradually lower the dam to simulate a breach using interfoam.

Could I use something like this for the dynamic part?

dynamicFvMesh solidBodyMotionFvMesh;  
  solidBodyMotionFvMeshCoeffs  
  {        
     cellZone                            lakeDam;        
     solidBodyMotionFunction    linearMotion;        
     linearMotionCoeffs        
     {            
           velocity        (1.0 0.0 0.25);        
      }  
   }

I'm new to OpenFOAM and would be happy about some pointers as to better understand this.

Thanks a lot!

Hello Florian,

You might want to have a look at this, it seems to be pretty close to what you are trying to achieve: https://www.youtube.com/watch?v=DoAwPhJ1nzU
