pTatin2d

Overview

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)
