What is in this repository?

• PUMI: parallel unstructured mesh infrastructure API User's Guide
• PCU: Communication and file IO built on MPI
• APF: Abstract definition of meshes, fields, and related operations
• GMI: Common interface for geometric modeling kernels
• MDS: Compact but flexible array-based mesh data structure
• PARMA: Scalable partitioning and load balancing procedures
• SPR: Superconvergent Patch Recovery error estimator
• MA: Anisotropic mixed mesh adaptation and solution transfer
• SAM: Sizing anisotropic meshes
• STK: Conversion from APF meshes to Sandia's STK meshes
• ZOLTAN: Interface to run Sandia's Zoltan code on APF meshes
• PHASTA: Tools and file formats related to the PHASTA fluid solver
• MTH: Math containers and routines
• CRV: Support for curved meshes with Bezier Shapes
• PYCORE: Python Wrappers (see python_wrappers/README.md for build instructions)
• REE: Residual based implicit error estimator

How do I get set up?

• Dependencies: CMake for compiling and MPI for running
• Configuration: Typical CMake configure and build. The example_config.sh shows common options to select, use a front-end like ccmake to see a full list of options
• Tests: the test/ subdirectory has tests and standalone tools that can be compiled by explicitly listing them as targets to make.
• Users: make install places libraries and headers in a specified prefix, application code can use these in their own compilation process. We also install pkg-config files for all libraries.

Contribution guidelines

• Don't break the build
• See the STYLE file
• If in doubt, make a branch
• Run the ctest suite
• Don't try to force push to master or develop; it is disabled

Who do I talk to?

• If you have a usage question or have found a bug please post an issue.
• Otherwise, email Cameron Smith and pumi@scorec.rpi.edu.
