Albany is an implicit, unstructured grid, finite element code for the solution and analysis of multiphysics problems. The Albany repository on the GitHub site contains hundreds of regression tests and examples that demonstrate the code's capabilities on a wide variety of problems including fluid mechanics, solid mechanics (elasticity and plasticity), ice-sheet flow, quantum device modeling, and many other applications.

Albany heavily leverages the Trilinos Framework, available at:

git clone https://github.com/trilinos/Trilinos.git

and optionally depends on the SCOREC Parallel Unstructured Mesh Infrastructure http://www.scorec.rpi.edu/pumi.

Albany supports the solution of very large problems (those over 2.1 billion degrees of freedom) using MPI, and also demonstrates the use of the Kokkos hardware abstraction package to support generic manycore computing across a variety of platforms - MPI + [threads, OpenMP, Cuda, Intel MIC].

In addition to supporting embedded sensitivity analysis and uncertainty quantification, Albany can be tightly-coupled to Dakota using the Trilinos TriKota package.

Detailed build instructions for both Trilinos and Albany are maintained on the Albany wiki at https://github.com/gahansen/Albany/wiki/Building-Albany-and-supporting-tools

Ths nightly build results for the Trilinos and SCOREC libraries along with Albany and the status of the Albany regression tests are posted on the Albany CDash site at http://my.cdash.org/index.php?project=Albany

The regression test suite is contained within the Albany repository in the directories:

/tests/small
/tests/large

These tests are stand-alone and also serve as nice examples about how to describe various multiphysics problems. They also serve as a template for developing new simulations.

Once Albany is built, the default test suite is executed by typing ctest within the build directory. Any individual test can be executed by moving into its sub-directory, and executing ctest in that sub-directory. Many Albany tests run in parallel using up to 4 MPI ranks.
