“…Because of the close relationship between B‐splines and Bernstein polynomials, we want to clarify the major differences between our method and the B‐spline method of Qian . The first difference lies in the properties of the density field definition itself.…”

“…In the B‐spline approach, the combination of global tensor product construction and required smoothness restricts how we can mesh the domain. In the work of Qian, the domain of interest is embedded in a box‐shaped domain. For complex domain shapes, this method can create some “extra” basis functions in the mesh whose support does not overlap the domain of interest.…”

“…10. This is a classical topology optimization problem of irregular design domain widely studied [21,22,[46][47][48]. Here, the design domain is divided into 90×60 cells and all the supports of CS-RBFs have a 3.5 mm radius.…”

“…In this approach, the voids are represented by coarser mesh while the solids by relatively finer mesh during the process [37,[40][41][42]. The concept of isogeometric analysis by Hughes et al [43] has been used to minimize overall cost by reducing the dependence to the initial FE grid and the post-processing efforts of converting to NURBS based CAD models for problems with complex geometry [44][45][46]. An efficient approach named multi-resolution topology optimization (MTOP) has been developed where the models for FE analysis and the design optimization are decoupled with different levels of discretization [36].…”
