nonlinearLESkit - proof of concept

Disclaimer: This repository is provided only as a proof of concept, devised for this thread: http://www.cfd-online.com/Forums/openfoam-programming-development/144714-problem-implementing-non-linear-sgs-model.html There is no warranty that this will work as intended. This only aims to prove how a new type of turbulence model, namely a non-linear LES model group, can be implemented to be used with OpenFOAM, without having to be integrated into OpenFOAM itself.

Branches

The following branches exist in this repository for the following OpenFOAM versions:

OpenFOAM 2.1.1: https://github.com/wyldckat/nonlinearLESkit/tree/of211
OpenFOAM 2.1.x: https://github.com/wyldckat/nonlinearLESkit/tree/of21x
OpenFOAM 2.3.0 to 2.3.x: https://github.com/wyldckat/nonlinearLESkit/tree/of23x

Building

Using Git

Go to your user folder:
```
mkdir -p $FOAM_RUN
cd $FOAM_RUN/..
```

Clone the repository and go into the cloned repository:

git clone https://github.com/wyldckat/nonlinearLESkit.git
cd nonlinearLESkit

Checkout the repository respective to the version of OpenFOAM you are using:

OpenFOAM 2.3.x:
```
git checkout of23x
```
OpenFOAM 2.1.x:
```
git checkout of21x
```
OpenFOAM 2.1.1:
```
git checkout of211
```

Build all of the libraries and utilities by running:

```
./Allwmake
```

The example case in exampleCaseChannel395 can be executed by running ./Allrun, but it will not work because the ngSgs field has not been updated to work as a volSymmTensorField.

Using Zip

Go to your user folder:
```
mkdir -p $FOAM_RUN
cd $FOAM_RUN/..
```
Get the Zip file for the repository respective to the version of OpenFOAM you are using:

OpenFOAM 2.3.x:

wget https://github.com/wyldckat/nonlinearLESkit/archive/of23x.zip

OpenFOAM 2.1.x:

wget https://github.com/wyldckat/nonlinearLESkit/archive/of21x.zip

OpenFOAM 2.1.1:

wget https://github.com/wyldckat/nonlinearLESkit/archive/of211.zip

Unzip the respective file and go into the respective folder, for example:

```
unzip of23x.zip
cd nonlinearLESkit-of23x
```

Build all of the libraries and utilities by running:

```
./Allwmake
```

The example case in exampleCaseChannel395 can be executed by running ./Allrun, but it will not work because the ngSgs field has not been updated to work as a volSymmTensorField.
