Graph, Geometric Order Enum, Scalar Field
Lattice, Geometric Order Enum, Scalar Field
About this Block
What it does: Generates an FE Mesh for beam based graph lattices. Lattice meshing takes less computation time than volume meshing and homogenization. Common uses:- Input in an FE Component.
- This method dramatically reduces the number of elements from a typical volume mesh, but it ignores certain mechanical behavior like edge effects and stress concentrations in the lattice.
- Discretization takes a Lattice type as an input.
- The Geometric order can be Linear, where integration points are added at every mesh intersection, or Quadratic, where integration points are added at the midpoint of the mesh edges.
- Linear Geometric order is faster but less accurate.
- Quadratic Geometric order is slower but more accurate. We recommend this option if you are using the results downstream.
- Subdivision input will split the original beam into equal length subdivisions.
- Use Trim Lattice to make sure the lattice elements lie within the volume of the lattice structure. If you get a warning about short lattice beams, use Collapse Lattice Vertices with a threshold much lower than the unit cell size.

Lattice, Geometric Order Enum, Scalar Field
Converts a graph-based Lattice into an FE Mesh by adding integration points of the desired order to the Lattice geometry.Inputs
| Name | Type | Description |
|---|---|---|
| Discretization | Lattice | The input geometric discretization. |
| Geometric order | Geometric Order Enum | The geometric order of the finite elements. |
| Subdivisions | Scalar Field | The number of finite elements that each beam in the Lattice will be subdivided into. If the provided Lattice is face-based, the faces will be remeshed with an updated average edge length equal to the current average edge length subdivided by the subdivisions input. |
