Prior to generate the mesh, the size of the elements in every geometrical entity has to be defined, to obtain an accurate discrete geometry. To do this, use the By Cordal Error tool (see Figure 43 and Figure 44).

The data used to assign define the error in fragmenting the geometry are shown in Figure 44.

Afterwards the mesh will be generated automatically by using a default element size of 8 and an Unstructured Size Transition of 0.5.

The outcome of the mesh generation process is the unstructured mesh shown in Figure 45, consisting of 4000 nodes and 16000 tetrahedral elements.
