This how-to discuss usage of Modules for Experiments in Stellar Astrophysics (MESA), an open-source 1D stellar evolution code at Phoebe cluster.
As the current Mesa SDK is already unpacked in the Phoebe shared filesystem, it is essential to configure the relevant environment variables:
export MESASDK_ROOT=/sw/phoebe/standalone/bh/mesasdk-22.6.1
source $MESASDK_ROOT/bin/mesasdk_init.sh
Create a suitable directory in your homedir, navigate to it using the 'cd' command, download the Mesa Star zip file, and ununpack it in that directory
mkdir -p ~/projects/mesaStar
cd ~/projects/mesaStar
wget https://zenodo.org/record/6547951/files/mesa-r22.05.1.zip
unzip ./mesa-r22.05.1.zip
There in ~/projects/mesaStar , we should see unpacked archive:
[user@login1 mesaStar]$ ll
total 2048836
drwxrwxr-x. 34 jose jose 54 11. kvě 21.35 mesa-r22.05.1
-rw-rw-r--. 1 jose jose 2098006607 27. srp 21.51 mesa-r22.05.1.zip
[user@login1 mesaStar]$
cd into unpacked archive and get current directory with command pwd.
[user@login1 mesaStar]$ cd mesa-r22.05.1/
[user@login1 mesa-r22.05.1]$ pwd
/home/jose/projects/mesaStar/mesa-r22.05.1
[user@login1 mesa-r22.05.1]$
export the path returned by command pwd as MESA_DIR:
export MESA_DIR=/home/jose/projects/mesaStar/mesa-r22.05.1
cd to $MESA_DIR directory and build mesa STAR:
cd $MESA_DIR
./install
Installation script can take some time as it performs checks if code is working properly.
Once the installation is done, message MESA installation was successful will be shown.
To avoid the need to export again environment variables as it was done above, one can modify own ~/.bashrc file .
Open own ~/.bashrc in nano (or in any editor of your choice)
nano ~/.bashrc
and append (do not forget to modify the MESA_DIR to reflect your mesa star installation directory! )
export MESASDK_ROOT=/sw/phoebe/standalone/bh/mesasdk-22.6.1
source $MESASDK_ROOT/bin/mesasdk_init.sh
export MESA_DIR=/home/jose/projects/mesaStar/mesa-r22.05.1
in all new shells, since now, mesa and mesaSDK will be activated automatically.
