(B)oundary representation for (E)volving (S)hape (S)imulations

 

Extract topology/geometry from a discrete model (polygonal model, finite element model, ...). The resulting model can be viewed as an organizational structure aimed at the preservation of geometrical features in the data.

Purpose: 

  • Construct initial topological/geometrical model (e.g. from an MRI isosurface).
  • Update topology for remeshing during a finite element simulation.

    • Special issues:

  • Introduction of decohesion or crack surfaces.
  • Wetting of boundary surfaces.

    •
