Objective:

Create an FE Mesh for a Trimmed Shell Lattice.

Applies to:

• Simulating lattices
• Shell Lattice is too complex to use the FE Lattice Mesh block (Invalid Mesh Topology error appears)

Procedure:

1. Start with a Trim Lattice block to create a lattice.

2. Open the Properties of the Trim Lattice block and extract the 'faces as mesh' chip into the Notebook.

• • To get to this property, expand thick lattice > lattice > faces as mesh.

3. Add a Simplify Mesh by Amount block.

• • Set the Amount to 0.00001.

4. Add an FE Surface Mesh block.

• • Set the Geometric order to Quadratic. 

And that’s it! You’ve successfully created the FE Mesh for a complex shell lattice.
