CONES
=================



**CONES** (Coupling OpenFOAM with Numerical EnvironmentS) is an application aiming to couple the CFD software OpenFOAM with any other open-source code.

Two main elements constitutes CONES:

1. Ensemble of :math:`m` simulations in OpenFOAM.

2. Code with the Data Assimilation (DA) algorithm.

Usage
-----

#. Set up a reference simulation in a folder named "case_orig".
   
   #. Generate the mesh and decompose it.
   
   #. Set up a topoSetDict that encompasses the regions of your domain where DA has to be performed.
   
   #. Run the topoSet OpenFOAM utility.

#. Use foamCloneCase to clone the reference simulation settings to generate the ensemble members
    
   #. Modify the ensemble members according to the initial distribution wanted

   #. Name each ensemble member folder as "en" followed by the id number of the ensemble member


#. Launch the eCones utility to print out the command to be run on terminal
