Underworld2 is a python-friendly version of the Underworld geodynamics code which provides a programmable and flexible front end to all the functionality of the code running in a parallel HPC environment. This gives signficant advantages to the user, with access to the power of python libraries for setup of complex problems, analysis at runtime, problem steering, and coupling of multiple problems.
Underworld2 is integrated with the literate programming environment of the jupyter notebook system for tutorials and as a teaching tool for solid Earth geoscience.
Underworld is an open-source, particle-in-cell finite element code tuned for large-scale geodynamics simulations. The numerical algorithms allow the tracking of history information through the high-strain deformation associated with fluid flow (for example, transport of the stress tensor in a viscoelastic, convecting medium, or the advection of fine-scale damage parameters by the large-scale flow). The finite element mesh can be static or dynamic, but it is not contrained to move in lock-step with the evolving geometry of the fluid. This hybrid approach is very well suited to complex fluids which is how the solid Earth behaves on a geological timescale.
This function simply enables Jupyter Notebook inlined matplotlib results. This function should be called at the start of your notebooks as a replacement for the Jupyter Notebook %matplotlib inline magic. It provides the same functionality, however it allows notebooks to be converted to python without having to explicitly remove these calls.
Returns the number of processes being utilised by the simulation.
Returns: Number of processors. Return type: unsigned
Returns the rank of the current process.
Returns: Rank of current process. Return type: unsigned
Creates an MPI barrier. All processes wait here for others to catch up.
