Acknowledgments

Special thanks go to:

  • William Fuentes (wiliam.fuentes@uni-norte.de): Implementation of the Hypo+ISA constitutive model.

  • David Masin: Implementation of the Clay Hypoplasticity constitutive model.

  • Andrzej Niemunis & Carlos Grandas-Tavera: Implementation of the Anisotropic Visco-HypoPlasticity (AVHP) constitutive model.

In addition, numgeo relies on several third party libraries:

  • SCOTCH, see 1\(^,\)2

  • METIS, see 3

  • OpenBLAS, see 45

  • HDF5

  • MUMPS, see 6

Without the free availability of such high quality software, the development of a new program like numgeo would hardly be possible. We would like to take this opportunity to thank the developers.
