module load hpc-env/8.3 module load AMR-Wind
Always remember: these commands are case-sensitive!
Using AMR-Wind
AMR-Wind is primarily executed by the command amr_wind. This command must be prefixed with "mpirun -np <number_of_allocated_cores>", since the program was built with MPI and accordingly only needs to be called with it. If you want to compute with AMR-Wind by only using CPU, you need to load the `intel` module. Should you want to additionally allocate any GPUs, the `intelcuda`-based module must be loaded.
To find out on how to use AMR-Wind you can just type in mpirun -np 1 amr_wind --help after loading the module to print out a help text to get you started:
