MacOS Catalina

Minimum System Requirements

In general, the following is required for MOOSE-based development:

  • GCC/Clang C++11 compliant compiler (GCC @ 4.8.4, Clang @ 3.5.1 or greater)

    • Note: Intel compilers are not supported.

  • Memory: 16 GBs (debug builds)

  • Processor: 64-bit x86

  • Disk: 30GB

Prerequisites

The following, is required to be installed before you can begin using MOOSE.

  • Xcode Command Line Tools (CLT). To install CLT on your machine, open a terminal and run:

    
xcode-select --install

    If you do not have both Xcode and CLT installed, you will be presented with a dialog box allowing you to install CLT. There are two choices, 'Get Xcode' and 'Install'. Choose 'Install' to install CLT. We will need Xcode as well... but it is easier to obtain CLT before Xcode.

    If by chance, xcode-select --install states you already have Xcode installed, your best bet is to continue on with the instructions.

  • Xcode. Using the App Store, search for and install Xcode. Once installed, you must open and run Xcode to finish the installation.

  • Download and install XQuartz

  • Catalina 10.15: moose-environment_osx-catalina_20191125_x86_64.pkg

Modify your Zsh Profile

During the installation of the moose-environment package, you have two opportunities to allow the installer to modify your zsh profile. This will allow the moose-environment module system and compiler stack to be made available by default with every new terminal window opened.

  • The first is available after clicking 'Customize' during the install. While in this pane, check the option "MOOSE Environment", and then continue by clicking 'Install'.

  • The second is after the installer has completed, where you will be presented with a pop-up window alerting you to either allow the installer to make this change, or to do nothing. If you choose 'Cancel' at this point, know that you are now responsible for altering your zsh profile yourself. In order to make the module system available, you must instruct your zsh profile to source the following file:

    
source /opt/moose/environments/moose_profile

    Once sourced, you can then load an appropriate compiler stack for MOOSE-based development:

    
module load moose-dev-clang
note:Finalize Installation

Once the installer has completed, and/or you chose to modify your zsh profile yourself, you must close any opened terminal windows, and re-open them to use the MOOSE environment.

Obtaining and Building MOOSE

Cloning MOOSE

MOOSE is hosted on GitHub and should be cloned directly from there using git. We recommend creating a directory named projects to put all of your MOOSE related work.

To install MOOSE run the following commands in a terminal.


mkdir ~/projects
cd ~/projects
git clone https://github.com/idaholab/moose.git
cd moose
git checkout master
note

The master branch of MOOSE is the stable branch that will only be updated after all tests are passing. This protects you from the day-to-day changes in the MOOSE repository.

Compile libMesh

MOOSE directly relies on the libMesh finite-element framework. Because of this strong tie MOOSE contains a particular version of libMesh that we have vetted for our users. To pull down and compile this version of libMesh you simply need to run a script in MOOSE:


cd ~/projects/moose
./scripts/update_and_rebuild_libmesh.sh
warning

Do not use sudo when running update_and_rebuild_libmesh.sh.

Compile and Test MOOSE


cd ~/projects/moose/test
make -j 4
./run_tests -j 4

If the installation was successful you should see most of the tests passing (some tests will be skipped depending on your system environment).
