Ptatin2D : dataset for run simulations presented in the article Slab pull driven South China Sea opening implies a Mesozoic Proto South China Sea

Overview of pTatin2D

pTatin2D is a software package designed for studying long time-scale processes relevant to geodynamics. The original motivation for this development was to provide the community with an open-source toolkit capable of studying high-resolution, two-dimensional models of lithospheric deformation.

Functionality

mixed finite elements (Q2-P1_disc) for the Stokes problem

material points for tracking Lagrangian state and history variables

energy equation solved with Q1 elements + SUPG

ALE formulations (with a variety of remeshing solutions)

extensible rheology components (currently supports: iso-viscous, Frank-Kamenetskii, Arrhenius, power-law, von Mises, Drucker Prager)

full support for spatio-temporal Dirichlet and non-zero Neumann boundary conditions

coupling with landscape evolution models

full support for Newton and Picard non-linear solvers

massively parallel implementation

pTatin2D leverages functionality from PETSc

Requirements

PETSc (only support for version 3.2)
