Minimal Surfaces
  Minimal surfaces in Euclidean 3-space and higher dimensions. The surfaces
  with vanishing mean curvature H = 0 are called minimal surfaces. The mean
  curvature H of a smooth surface in R3 is the mean of the two
  principal curvature values. Locally, such surfaces are shaped like a saddle and
  minimize surface area.
  Minimal surfaces appear in various mathematical disciplines like differential geometry,
  calculus of variations and partial differential equations, as well as in other
  sciences like crystallography and chemistry.

  As a guide, meshes should have no holes, no degenerate triangles and
  elements, no duplicate vertices. Surfaces should have meshes with an adjacency
  relation.
