The run time of the simulations is dependent on the input
parameters. In general, solution for the higher loads takes longer
because more iteration is needed to converge. Also, the solution
for rough surfaces is generally slower than the smooth solution,
because the asperity pressure must be calculated in each loop. The
typical run time on an Intel i7 3.47 GHz machine for the chosen
domain and grid setup is generally between 20 and 100 minutes
depending on the input.
The final results consist of the hydrodynamic, asperity, and
total pressure distributions as well as the film profile. Based on
these results, the central and the minimum film thickness are
easily determined. Also predicted is the asperity load ratio which
is the ratio of the load carried by the asperities to the total
normal load.
