* CREST 3.0 IS AVAILABLE! *
CREST 3.0 is a major overhaul of the previous code versions. A large part of the original source code was rewritten to implement calculators, optimization, and molecular dynamics routines directly, rather than relying only on the xtb program as a subprocess.
Consequently, there are performance improvements and a significant reduction of I/O operations.
Features include:
* Major code refactoring
* New input file reader
* Energy- and gradient-based interface for calculations
* Standalone ANCOPT implementation (RF optimizer with BFGS update step in approximate normal coordinates)
* Standalone MD and metadynamics module
* Standalone implementation of geometrical constraints
* New minimum energy crossing point (MECP) algorithm (see JCTC, 2022, 18 (10), 6370-6385.)
* Integration of the tblite submodule
* Integration of a GFN0-xTB submodule (see J. Phys. Chem. Lett. 2023, 14, 19, 4440–4448)
* Integration of the TOML-F parser
* Integration of a GFN-FF submodule
* Implementation of a multi-layered multi-center ONIOM calculator (see J. Phys. Chem. B 2024, 128, 13, 3145–3156, @paw61)
* Proper unit tests for the CMake build
* MSREACT mode (@gorges97)
* Implementation of X-HCFF (@zellerf)
* Effective Hessian calculator (@GereonFeldmann)
* and more ...
