Ubuntu - gcc

If numgeo is used in combination with gcc the installation steps are different for Ubuntu 20.04 and Ubuntu 22.04. Make sure to follow the steps in the respective section.

Windows WSL

If Ubuntu is installed via WSL on Windows, the steps are the same as for a "native" Ubuntu installation.

numgeo uses a collection of third party libraries:

• gcc: https://gcc.gnu.org/
• gfortran: https://gcc.gnu.org/wiki/GFortran
• MUMPS: MUltifrontal Massively Parallel sparse direct Solver, https://mumps-solver.org/index.php.
• SCOTCH (partitioning): The SCOTCH distribution is a set of programs and libraries used by the solver MUMPS which implement the static mapping and sparse matrix reordering algorithms. https://www.labri.fr/perso/pelegrin/scotch/
• OpenBlas: Optimized BLAS library based on GotoBLAS2 1.13 BSD version. https://www.openblas.net/

Depending on the version of Ubuntu the versions of these third party libraries changes as well.

MUMPS

The MUMPS library is already included in the numgeo executable and does not need to be installed.
