cgnsUtilities

This repository contains a single program called cgns_utils that provides many useful functions for working with cgns grids.

Installation Instructions

First, copy the default configuration file to the required name. For example, to use gfortran:

cp config/defaults/config.LINUX_GFORTRAN.mk config/config.mk

Open and edit the config file. You many have to adjust the CGNS_INCLUDE_FLAGS and CGNS_LINKER_FLAGS to match your installation of the CGNS library. You may also specify the c-compiler with the CC variable and the flags for the c-compiler with CFLAGS. The C-compiler is only used for the compiler f2py wrapper. The Fortran compiler may be specified with the FC variable and the corresponding flags with the FFLAGS variable. It has been tested with both Intel and GNU Fortran compilers.

To compile, simply type

make 

If all goes well, you will see

which indicates a successful compilation.

To install, type

pip install .

or optionally with the --user flag if you are not using a virtual environment. A console script called cgns_utils is provided, which should be installed automatically and available without modifying your $PATH.
