Illustration of the mesh updating strategy with minimal remeshing: (top-left) design variables \({\mathbf {s}}^e\) defined as a subset of edge control points DOF; (top-right) edge control points displacement \({\mathbf {s}}^e_{cp} = {\mathbf {C}}_s^e \; {\mathbf {s}}^e\) ; (bottom-left) edge FE nodes displacement \({\mathbf {s}}^e_{fe} = ({\mathbf {C}}_{FFD}^e)^T \; {\mathbf {s}}^e_{cp}\) ; (bottom right) all FE nodes displacement \({\mathbf {s}}_{fe} = {\mathbf {C}}_{m} \; {\mathbf {s}}^e_{fe}\)
