Examples

Defaults from seeds file

> geom_fromVoronoiTessellation < 20grains.seeds > 20grains_161616_111.geom

cubic geometry
Figure 1: Cubic geometry of exemplary seeds file with grid 16 x 16 x 16 and size 1.0 x 1.0 x 1.0.
In this example, the grid point number is taken from the seeds file as 16 x 16 x 16. Since no size is specified, the default of 1.0 along the longest edge results in a physical size of 1.0 x 1.0 x 1.0 for the resulting geometry.

Arbitrary grid and size

> geom_fromVoronoiTessellation -g 32 16 8 -s 1 0.5 0.25 < 20grains.seeds > 20grains_32168_105025.geom

slab geometry
Figure 2: Slab geometry of exemplary seeds file with grid 32 x 16 x 8 and size 1.0 x 0.5 x 0.25.
The next example explicitly overrides the grid and specifies a size maintaining (by choice) an equidistant grid. Since the physical size of the geometry gives different relative positions of the seed points compared to the former example, a different geometry results from the tessellation.

Generating material configuration

The <microstructure> and <texture> parts of a material.config are automatically included within the header part of the resulting geometry file. Therefore, a geometry file can be directly linked from the material.config by using the » {theFile.geom} « inclusion format.
