If the build process is successful, the executable will be in build/src/executables/ReMKiT1D. ReMKiT1D requires a config.json file as input. Assuming a valid config file is available, the code can be run from the executable directory using, for example:
mpirun -np [num_procs] ./ReMKiT1D
where [num_procs] should be set to the desired number of processes. An alternative path to the config file can be specified using the command line option
-with_config_path=/path/to/config/file.json
