Foam-Extend
===========

De acordo com a `página do Foam-Extend <https://openfoamwiki.net/index.php/Installation/Linux/foam-extend-4.0>`_,
"*The foam-extend project is a fork of the OpenFOAM® open source library for
Computational Fluid Dynamics (CFD). It is an open project welcoming and
integrating contributions from all users and developers. Previously known as
OpenFOAM-dev and OpenFOAM-extend, it contains bug fixes and performance
improvements, as well as extensions and additional features provided by
community contributors (see file ListOfContributors), such as dynamic mesh and
topological change support, turbomachinery extensions including general grid
interpolation (GGI), cyclic GGI and mixing plane, block-coupled matrix support,
implicitly coupled conjugate heat transfer and other physics coupling, finite
area method, comprehensive dynamic mesh (motion and topological changes)
capability and GPU support*".

Versões Disponíveis
-------------------

* foam-extend/4.0 (default)
* foam-extend/4.1


Submissão de Jobs em Paralelo
-----------------------------

Crie um arquivo chamado, por exemplo, *submit_paral_jobs.sh*.

.. code-block:: bash

   #!/bin/bash
   #SBATCH -t 24:00:00 -n 4

   export INPUT="circCylinder3dHex.zip"
   export OUTPUT="*"

   module load foam-extend
   job-nanny ./run.sh
  

O conteúdo do arquivo *run.sh* seria algo como:

.. code-block:: bash

   #!/bin/bash

   unzip circCylinder3dHex.zip
   decomposePar
   mpirun -n 4 moveDynamicMesh -parallel   

Para submeter o processo, basta usar o comando:

.. code-block:: bash

  sbatch submit_paral_jobs.sh


Submissão de Jobs Seriais
-------------------------

Crie um arquivo chamado, por exemplo, *submit_serial_jobs.sh*.

.. code-block:: bash

   #!/bin/bash
   #SBATCH -t 24:00:00

   export INPUT="foam-extend-cavity.zip"
   export OUTPUT="cavity.zip"

   module load foam-extend
   job-nanny ./run.sh

O conteúdo do arquivo *run.sh* seria algo como:

.. code-block:: bash

   #!/bin/bash

   # unpack input file
   unzip foam-extend-cavity.zip

   blockMesh
   icoFoam

   #pack all results
   zip cavity.zip *

Para submeter o processo, basta usar o comando:

.. code-block:: bash

   sbatch submit_serial_jobs.sh
