The tetrakaidecahedron (shown below) is a polyhedron studied in conjunction with foams and minimal surface area, space-filling shapes. The tetrakaidecahedron has 14 faces (6 quadrilateral and 8 hexagonal) and 24 vertices [1].

 

In 1887, Lord Kelvin proposed that the tetrakaidecahedron was the best shape for packing equal-sized objects together to fill space with minimal surface area. Kelvin thought about this problem in the context of the bubbles which make up a foam [1]. Kelvin’s proposed tetrakaidecahedron actually had some slightly curved faces which improved upon the typical flat-faced polyhedron pictured above

 

In this tutorial, you will learn how to create a tetrakaidecahedron using Ansys DesignModeler.

The Thin/Surface feature allows you to convert solids into thin solids or surfaces. The feature can operate on both active and frozen bodies. Typically, you will select the faces to remove, and then specify a face offset that is greater than or equal to zero (>=0).

Some import types (ACIS and AutoCAD) allow you to specify the units of the imported model. Before clicking Generate, you may be able to change the model units from the Details View, depending on the type of import. Note that some model types store their units, so no Model Units property will appear when importing them.

The Connect feature may be used to align and possibly join a set of vertices, edges or faces. The alignment takes the form of a stretching and aligning of existing geometry.

The Mid-Surface feature allows the creation of Surface bodies that are midway between existing Solid body faces. The resulting surface body/bodies have a Thickness property which defines the “thickness” that surface body represents.
