About this Block
The Parametric Voronoi Domain block creates an FE Domain, parameterized with design parameters for a Voronoi lattice with variable cell size and lattice thickness. The block uses an FE Solid Mesh as an input Mesh. After field optimization, it will apply optimized values for the lattice thickness and cell size to the design space. The Parametric Voronoi lattices use a theoretical relationship between the relative density of an open-celled foam and the resulting mechanical properties. Common uses :- This block is an input to the Parametric FE Model block.
- Implicit View - allows you to view the resulting geometry.
- Property Fields - allows a user to view the mechanical properties of the structure across the design space before performing field optimization.
- State Fields - allows a user to view values of the design parameters across the design space before performing the field optimization.
- The cell size is the average spacing between the center points of the Voronoi lattice.
-
You can use the initial value inputs to the domain blocks in 2 ways:
- Adjust the Initial Beam Thickness and the Initial Cell Size to view the geometry generated for the upper/lower bounds to ensure printability before running a field optimization.
- The starting point from which the optimization continues.

Create a Parametric FE Domain for a Voronoi Lattice with the following design parameters: cell size and beam thickness. The material model is homogenization-based so the model accuracy will improve as the cell size is reduced. Inputs| Name | Type | Description |
|---|---|---|
| Mesh | FE Mesh | The finite element mesh that defines the design space. |
| Material | Isotropic Material | Material that the voronoi lattice is comprised of. |
| Min cell size | Scalar Field | The minimum allowable cell size for the voronoi lattice. |
| Max cell size | Scalar Field | The maximum allowable cell size for the voronoi lattice. |
| Initial cell size | Scalar Field | The initial cell size for the voronoi lattice. this defines the starting point of the optimization. values exceeding the min/max bounds will be clamped. |
| Min thickness | Scalar Field | The minimum allowable beam thickness for the voronoi lattice. |
| Max thickness | Scalar Field | The maximum allowable beam thickness for the voronoi lattice. |
| Initial thickness | Scalar Field | The initial beam thickness for the voronoi lattice. this defines the starting point of the optimization. values exceeding the min/max bounds will be clamped. |
| Filter size | Scalar Field | A length measure that is used to control the smoothness of the design parameter field. a lower bound of 0 will be enforced. if not specified, a default will be estimated based on the model size. |
