Figure

Figure 1. Parameters of the lithosphere used to derive the thin-sheet equations. S is the crustal thickness and L the mantle thickness
Figure 2. Viscosity profile with depth used for the linear viscous 3-D model (solid black line) and depth-averaged viscosity profile used for the linear viscous thin-sheet model (dashed black line)
Table 1. Model parameters applied in the thin- thin-sheet (TS) and 3-D simulations. H is reported for the background strain rate of 10 −15 s −1 .
Table 2. Results of performance test on ‘Achilles’ (University of Lausanne). Each solver (direct MUMPS, iterative ASM, algebraic and geometric multigrid) was tested using both types of elements (Q 1 P 0 and Q 2 P– 1 ) and three different resolutions.
