Hermes is being developed by a community around the hp-FEM group at the University of West Bohemia and the University of Nevada, Reno (UNR). Everybody is welcome to contribute.
Each successful contributor becomes a co-author of the library.

1. Overview
Quick description
Hermes2D is a C++ library for rapid development of adaptive hp-FEM / hp-DG solvers. Novel
hp-adaptivity algorithms help solve a large variety of problems ranging from ODE and stationary
linear PDE to complex time-dependent nonlinear multiphysics PDE systems.
Highlights of Hermes capabilities
- mathematical point of view
- L2, H1, HCurl, HDiv Sobolev spaces approximation with element-wise polynomial degree up to 10
- Hanging nodes of arbitrary order
- Multimesh = assembling over component-specific meshes without projections or interpolations in multiphysics problems
- Time-adaptive capabilities with a large number (~30) of pre-implemented Runge-Kutta methods
- Coupled problems solved together with hp-DG and hp-FEM
- Adaptivity based on reference solution and local projections
- Calculations with physical quantities defined in different subdomains
- implementation point of view
- OpenMP parallelization
- Unified library for handling both real and complex problems using advanced C++ templating
- Own OpenGl based visualization & VTK outputs of meshes, spaces, solutions
- Division of the library's code into easy-to-manage namespaces
- XML save / load of the most important classes using provided XML schemas
- Well arranged doxygen documentation
- Exception safe API
2. Current release
Hermes 2.0 released on February 19th, 2013
- Rapid speedup of assembling and I/O
- Cleaner, well-documented code
- New way of testing, memory-leaks detection, speed optimizations
- Exception-safe API, bugfixes, etc..
