Algorithm 2
From: Thermal modeling of subduction zones with prescribed and evolving 2D and 3D slab geometries
Picard iterative scheme employed to compute the approximate solution of the nonlinear system equations (27) to (29). Here \(\Vert \cdot \Vert _{{L_{2} }} = \sqrt{( \cdot , \cdot )}\) is the \(L_{2}\) norm measure and TOL \(\ll\) 1 is the convergence threshold tolerance (selected to be TOL = \(10^{-6}\) in this work).
