Abstract

The invention notably relates to a computer-implemented method for designing a three-dimensional (3D) finite element mesh of a 3D part that comprises a lattice structure. The method comprises providing a solid representation of the 3D part, providing a regular tiling of cells, each cell comprising a finite element mesh, superposing the regular tiling of cells with the solid representation of the 3D part, partitioning (S40) the cells into two groups. A first group of cells, each in contact with the solid representation of the 3D part, and a second group of cells, none in contact with the solid representation of the 3D part. The method also comprises finite element meshing a boundary of the solid representation of the 3D part, extracting a boundary finite element mesh of the first group of cells, computing a Boolean union of the finite element mesh of the boundary of the solid representation of the 3D part and of the extracted boundary finite element mesh of the first group of cells, finite element meshing a volume of the computed Boolean union and merging the finite element meshes of meshed volume of the computed Boolean union and the cells of the second group of cells.
