For a given circle and a given polyhedron: you have first to convert the representation of your polyhedra into a face representation (in Matlab, use convex hull operator "convhull" for that). 11 is now available and extends the multi-simulation solver concept even further by introducing a fluid-structure interaction (FSI) solver (in addition to the existing built-in multiphysics, OpenFOAM, and FEniCS solver integrations). It is called an icosahedron because it is a polyhedron that has 20 faces (from Greek icosa-meaning 20) When we have more than one icosahedron they are called icosahedra When we say "icosahedron" we often mean "regular icosahedron" (in other words all faces are the same size and shape), but it doesn't have to be - this is also an icosahedron.
