The bidirectional improvement of level set method topology optimization

This paper research the Topology optimization based on level set method. Existing level set topology optimization method based on the reaction diffusion equation does not satisfy the volume constraints and convergence of objective function when solve some model optimization. According to this phenomenon, this paper proposes a new level set topology optimization algorithm based on the reaction diffusion equation, this algorithm can control the direction of the level set function and do bidirectional optimization which the objective function under the condition of volume constraint can reduce material or increase the material. Eventually, the results of optimization can become steady.
