and some models run much faster than others depending on the number of cells in the model, type of
solver used and physics of the problem.
Combustor_71m, f1_racecar_140m and open_racecar280m are large models that require two or more
servers for sufficient memory capacity. The results for these cases start with the first valid result obtained
for the specific problem.
