PHIMATS (Phase-field Multiphysics Materials Simulator) is a finite element library in C++, originally designed for simulating mesoscale hydrogen-material interactions using phase-field based representative volume element (RVE). However, its modular design allows it to be applied to a wide range of multiphysics problems.
- Phase-field based RVE models for hydrogen-material interactions
- Solid mechanics
- Heat and mass transfer modeling
- Pre/Post processing via Python interface for flexible input/output handling
- Object-oriented C++ with inheritance & polymorphism for modularity
- HDF5-based data storage for efficient data handling
- XDMF format support for visualization in ParaView
- Companion theory manual: Finite Element Theory for PHIMATS
- Publications & examples: Available in the
CaseStudiesdirectory - Doxygen documentation: Online API Reference
To balance simulation flexibility with high performance, PHIMATS is compiled as a library (libphimats.so), which must be linked with a custom driver code in a simulation folder.
Example driver codes and hands-on tutorials can be found in the CaseStudies directory. The makefile in the subdirectories handles the compilation and linking automatically. These examples demonstrate how to use PHIMATS for various hydrogen-material interaction simulations and related applications.
