Normalized CPU time vs. the number of fluids for the test described in Section 3.6. As expected, the complexity of MDIRK is ﹩{ \mathcal O }(N)﹩. For comparison, we also include the results of the multifluid second-order fully implicit method (RK2Im) from Huang & Bai (2022), which has complexity ﹩{ \mathcal O }({N}^{3})﹩.
