MPAS has not been brought across from Raijin to Gadi
The Model for Prediction Across Scales (MPAS) is a collaborative project for developing atmosphere, ocean and other earth-system simulation components for use in climate, regional climate and weather studies. [[1]]. The Atmospheric component of the model is now available for use on Raijin.

Building on Gadi
MPAS7 on Gadi requires no code modifications, although you will need to install its dependency PIO
Installing PIO
module load intel-compiler openmpi
module load netcdf/4.7.3p pnetcdf
# Installation directory, set as desired
export PIO_DIR=/scratch/$PROJECT/$USER/pio
wget https://github.com/NCAR/ParallelIO/releases/download/pio2_5_2/pio-2.5.2.tar.gz
tar xvf pio-2.5.2.tar.gz
cd pio-2.5.2
CC=mpicc FC=mpif90 ./configure --enable-fortran --prefix $PIO_DIR && make check
# I see an error in 'test_pioc'
make install
cd ..
Building MPAS
module load intel-compiler openmpi
module load netcdf/4.7.3p pnetcdf
git clone https://github.com/MPAS-Dev/MPAS-Model
cd MPAS-Model
# Set to wherever you installed PIO
export PIO=$PIO_DIR
make ifort CORE=atmosphere USE_PIO2=true
make clean CORE=init_atmosphere
make ifort CORE=init_atmosphere USE_PIO2=true
Running
See the User's Guide for details on how to run the model. A number of idealised test cases as well as meshes for different resolutions are available from the MPAS download site. The top-level directory has all of the TBL, DBL and namelist files required to run MPAS
A sample PBS script to run the model:
#!/bin/bash
#PBS -l ncpus=4
#PBS -l mem=16gb
#PBS -l walltime=1:00:00
#PBS -l jobfs=50gb
#PBS -l wd
#PBS -W umask=0022
module load openmpi
# Add your PIO library's 'lib' directory here
export LD_LIBRARY_PATH=/scratch/$PROJECT/$USER/pio/lib:$LD_LIBRARY_PATH
# Create initial conditions
mpirun ./init_atmosphere
# Run the model
mpirun ./atmosphere_model
