a Geometry and coefficients for a simplified 2D subduction zone model specifically for the proposed new benchmark. All coefficients and parameters in the graph are nondimensional. The decoupling point is indicated by the star. b Example mesh (upper frame) constituted of triangles for the new benchmark geometry with zoom in (lower frame). This particular example is for TerraFERMA with 83,935 degrees of freedom in the heat equation. Size of the finite elements ranges from 1 km near the coupling point where the solution gradients are highest to up to 6 km away from thermal boundary layers. Red solid line is the top of the slab. Dashed red line is the slab Moho. c) Initial condition for the time-dependent benchmark problem
