DESIGN OF A 3D FINITE ELEMENT MESH OF A 3D PART THAT COMPRISES A LATTICE STRUCTURE
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...

| description | 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, where 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 computing a Boolean union of the first group of cells and the solid representation of the 3D part, the Boolean union forming a volume, finite element meshing the volume of the computed Boolean union while preserving the set of faces of the first group of cells that are shared with the second group of cells, and merging the finite element meshes of the cells of the second group and the meshed volume of the computed Boolean union. |
