Block under compression: Comparison of computational times for different discretizations. Timings were obtained using (a) 48 cores and (b) 192 cores on ARCHER, UK. Coarser grids, see Table 1, are used for Taylor–Hood elements ℙ₂ – ℙ₁ to compare computational times for a similar number of degrees of freedom (DOF).
