Abstract: A computer-implemented method for designing a modeled object representing a mechanical part formed in a material having an anisotropic behavior with respect to a physical property including obtaining a first mesh, a density field representing at least boundary of the modeled object, and an orientation tensor field representing a desired anisotropic behavior. The method further includes, for each ith principal direction of the orientation tensor field, computing an anisotropic reaction-diffusion pattern on an ith mesh, the ith mesh having higher resolution than the first mesh and being bounded by the boundary of the modeled object. The method further includes combining by Boolean operations the computed anisotropic reaction-diffusion patterns projected on a second mesh.

Abstract: A computer-implemented method for designing a 3D modeled object representing a mechanical part. The method comprises providing a 3D finite element mesh and associated data. The data associated to the 3D finite element mesh comprise one or more forces each forming a respective load case, one or more boundary conditions, and one or more parameters related to a material. The method further comprises performing a topology optimization based on the finite element mesh and on the data associated to the finite element mesh. The topology optimization is performed among candidate material distributions each corresponding to a solution of a system of reaction-diffusion equations. This forms an improved method for designing a 3D modeled object representing a mechanical part formed in a material.
