The experimental geometry was modeled based on the coordinates provided by Kalala (2008)[8]. After running the Rocky case as specified, the results can then be compared to the experimental values. This validation case demonstrate that such a modeling scheme still maintains reasonable accuracy in the geometry volume compared to experimental measurements, as we can see in Table 2.8: Comparison between the experimental and simulation geometry volume.

Table 2.8: Comparison between the experimental and simulation geometry volume.

Geometry	Volume ()	Relative Error (%)
Unworn reference	0.1131	-
Worn Experimental	0.0967	-
Worn Rocky simulation	0.0956	-0.8

It is also possible to verify that the wear profiles between the experimental geometry and simulation are similar (Figure 2.14: Comparison between profiles: Unworn reference (Yellow), Worn Experimental (Purple) and Worn Rocky simulation (Orange). ).
