Serac is a 3D implicit nonlinear thermal-structural simulation code. Its primary purpose is to investigate multiphysics abstraction strategies and implicit finite element-based algorithm development for emerging computing architectures. It also serves as a proxy-app for LLNL's Smith code and heavily leverages the MFEM finite element library.

This project is under heavy development and is currently a pre-alpha release. Functionality and interfaces may change rapidly as development progresses.


Build, run, and design documentation can be found at readthedocs.
