Global mantle circulation computation using mantle tomography to infer density distributions in the mantle and solving Stokes equation (modified from Becker and Faccenna, 2011), see (cf. Hager and O’Connell, 1981; Zhong et al., 2000; Becker, 2006). Visualization with Paraview (Kitware, Inc., 2006).
