HOPR (High Order Preprocessor) is an open-source software for the generation of three-dimensional unstructured high-order meshes. These meshes are needed by high-order numerical methods like Discontinuous Galerkin, Spectral Element Methods or pFEM, in order to retain their accuracy if the computational domain includes curved boundaries.
HOPR has been developed by the Numerics Research Group (NRG) lead by Prof. Claus-Dieter Munz at the Institute of Aerodynamics and Gasdynamics at the University of Stuttgart, Germany.
This is a scientific project. If you use HOPR for publications or presentations in science, please support the project by citing our publications given in REFERENCE.md.
See the full documentation including usage instructions and tutorial for HOPR is the User Guide.
For installation instruction see the user guide section Installation or the source file.
In case you have question regarding HOPR, want to report bugs or contribute to the project you can use the mailing list hopr-project@listserv.uni-stuttgart.de. You can also subscribe to the mailing list here.
The Mesh Format is described as part of the User Guide or can be viewed as a separate PDF
