Fig. 15 — Twisting column test: mesh convergence for (A) hexahedral and (B) tetrahedral elements. Shown are displacements u_x, u_y, and u_z at tip D versus time. For experiments depicted the incompressible formulation with MINI elements was chosen. At finer levels of refinement ℓ = 3, 4, 5 (in black) results converge to a solution for each displacement direction.
