Puffin dipping dynamics
Provided with a three-dimensional scan of an Atlantic Puffin (Fratercula arctica) and position data as a function of time for several key points on the puffin's body throughout a dive into sea water, a moving surface mesh was needed to be used in a boundary element method analysis. A method was...
