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

Install the following using dnf

sudo -E dnf install gcc \
  gcc-c++ \
  gcc-gfortran \
  tcl \
  tk \
  findutils \
  make \
  freeglut-devel \
  libXt-devel \
  libX11-devel \
  m4 \
  blas-devel \
  lapack-devel \
  git \
  xz-devel

Download and install one our redistributable packages according to your version of Fedora.

• Fedora 31: moose-environment_fedora-31_20191125_x86_64.rpm

Once downloaded, the package can be installed via the rpm utility:

sudo rpm -i moose-environment_fedora-*.rpm

Once complete, the on-screen instructions will ask you to close any opened terminal windows. So, in a new terminal window, attempt to load the moose-dev-gcc module:

module load moose-dev-gcc

If no errors were generated running the above command, you have successfully installed moose-environment package. While optional, please read the next section about modifying your Bash Profile. If you do not, you will have to perform the above module load moose-dev-gcc command each and every time you open a new terminal window before performing any MOOSE-based development.

Modify your Bash Profile

For bash users (the default shell for most users), if you wish to have the moose-dev-gcc module loaded automatically with each new terminal session, copy and paste the following (which will append the necessary module load command to the end of your bash profile):

• GUI Users:

  
  echo "module load moose-dev-gcc" >> ~/.bashrc
  

• Console Users:

  
  echo "module load moose-dev-gcc" >> ~/.bash_profile
  

  note:Both profiles?

  Some distributions are configured to source both of these files regardless of the method you use to log into your machine (meaning you may only need to modify one). Your milage may vary.

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

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

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).
