We present a conformal bisection procedure for
local refinement of 4D unstructured simplicial meshes with
bounded minimum shape quality. Specifically, we propose a
recursive refine-to-conformity procedure in two stages, based on
marking bisection edges on different priority levels and defining
specific refinement templates. Two successive applications
of the first stage ensure that any 4D unstructured mesh can
be conformingly refined. In the second stage, the successive
refinements lead to a cycle in the number of generated similarity
classes and thus, we can ensure a bound over the minimum
shape quality. In the examples, we check that after successive
refinement the mesh quality does not degenerate. Moreover, we
refine a 4D unstructured mesh and a space-time mesh (3D + 1D)
representation of a moving object.
