Efficient Finite Element Methodology Based on Cartesian Grids: Application to Structural Shape Optimization

Figure 5

Comparison of two different geometries 𝑖<𝑗 during an optimization process. The data for the green elements evaluated for geometry 𝑖, in both meshes, are reused in geometry 𝑗.

(a)   Geometry  i  of the optimization process

(b) Geometry j of the optimization process

(c) Geometry i of the optimization process, an h-adaptive mesh
