Query: Combined parameterization of material distribution and surface mesh for
  stiffener layout optimization of complex surfaces   Stiffener layout optimization of complex surfaces is fulfilled within the
framework of topology optimization. A combined parameterization method is
developed in two aspects. One is to parameterize the material distribution of
the stiffener layout by means of B-spline. The other is to build the mapping
relationship from the known 3D surface mesh of the thin-walled structure to its
parametric domain by means of mesh parameterization. The influence of mesh
parameterization upon the stiffener layout is discussed to reveal the matching
issue of the combined parameterization. 3D complex surfaces represented by the
triangular mesh can be dealt with even though analytical parametric equations
are not available. Some numerical examples are solved to demonstrate the direct
advantage and effectiveness of the proposed method.
