Abstract
A method of generating an infill geometry of a body, comprises providing a driver mesh comprised of tetrahedral elements, and providing a reference unit cell mesh configured to fit exactly within a regular tetrahedron having triangular faces. The reference unit cell mesh is symmetric with respect to the arrangement of cell mesh nodes on the triangular faces. The method includes mapping the reference unit cell meshes respectively into the tetrahedral elements of the driver mesh, through the use of basis functions defined on each of the tetrahedral elements in a manner causing adjustment of the reference unit cell meshes to conform respectively to the tetrahedral elements, and resulting in an infill geometry comprised of mapped unit cell meshes. The method additionally includes stitching together the mapped unit cell meshes to result in a stitched mesh, and optionally smoothing the stitched mesh through one or more mesh smoothing operations.
