Simp method for topology optimization

WebbTopology optimization using the SIMP approach Element wise design parametrization – or, as it is usually called, the SIMP approach – allows to formulate a material distribution problem of the type first discretize, then optimize. Based on the finite element discretization, we use element wise design variables 𝜌 e with the property WebbIt is well known that the direct application of the SIMP method for solving a topology optimization problem may result in a structure containing a checkerboard-like material distribution (e.g. Diaz and Sigmund [7]). To circumvent this problem, several regularization schemes were proposed in the literature.
