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 \(m\) simulations in OpenFOAM.

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

Usage

1. Set up a reference simulation in a folder named “case_orig”.

   1. Generate the mesh and decompose it.

   2. Set up a topoSetDict that encompasses the regions of your domain where DA has to be performed.

   3. Run the topoSet OpenFOAM utility.

2. Use foamCloneCase to clone the reference simulation settings to generate the ensemble members

   1. Modify the ensemble members according to the initial distribution wanted

   2. Name each ensemble member folder as “en” followed by the id number of the ensemble member

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