For more information see the Goma website

Changes in version 6.2

• Many bug fixes
• Stratimikos support
• Log conformation tensor stress model
• Hysing and Denner surface tension models for level set
• Suspension balance updates
• Updated SUPG for species
• Quadratic triangles
• And more...

Changes in version 6.1

• Automatic creation of brk files (see docs/parallel_integration.md)
• Bug fixes (mostly MPI related bugs)
• Epetra is now a supported matrix format (see docs/epetra_matrix_format.md)
• MUMPS is now supported through Amesos
• An experimental build script to build library dependencies is available under scripts/

Build Instructions

Get the Goma source code

Run the command

git clone https://github.com/goma/goma

Get the prerequisites

Goma requires many third party libraries (TPLs, listed in scripts/README.md) which can be built automatically with the build script located in the scripts directory.

Build script requirements

The build-goma-dependencies.sh script relies on several packages readily available in many repositories.

For Ubuntu this will install the necessary packages to run the script:

sudo apt-get install git build-essential m4 zlib1g-dev libx11-dev gfortran

For CentOS

sudo yum install git patch gcc gcc-c++ gcc-gfortran m4 make wget bzip2 tar zlib-devel libX11-devel

The scripts README gives a more specific list of minimum requirements. Please ensure the script requirements are met before attempting to use it.

Build Everything

To build third party libraries (TPLs):

cd goma/scripts

./build-goma-dependencies.sh [-j NUM_PROCS] GOMA_TPL_INSTALL_DIRECTORY

Where -j NUM_PROCS is optional to run the build with multiple processors and GOMA_TPL_INSTALL_DIRECTORY is where you would like the third party libraries to be installed.

Add the openmpi bin directory to your PATH, the trilinos bin directory to your path, and the openmpi lib directory to your LD_LIBRARY_PATH See scripts/README.md for more details on setting paths.

Finaly to build goma copy the settings.mk-example to settings.mk edit GOMA_LIBS to point to your TPL directory, and make sure the trilinos and openmpi paths/versions are correct.

Then to build goma run:

make

The goma executable will be built in the [path to goma]/bin directory

Optionally goma can be installed with

make install PREFIX="/path/to/install/"

default prefix if unspecified is /usr/local

Environment Variables

OpenMPI should be added to the path and library path. If the build script was used to build openmpi you would use something like:

export LD_LIBRARY_PATH="/[path to gomalibs]/openmpi-4.0.2/lib:$LD_LIBRARY_PATH"
export PATH="/[path to gomalibs]/openmpi-4.0.2/bin:$PATH"

SEACAS tools from Trilinos (e.g. aprepro and blot) should be added to your path

export PATH="/[path to gomalibs]/trilinos-12.18.1/bin:$PATH"  

For netcdf utilities such as ncdump add netcdf executables to your path

export PATH="/[path to gomalibs]/netcdf-c-4.7.3/bin:$PATH"
