forceDirCoeffs

This repository provides a function object based on forceCoeffs from OpenFOAM(R), but with the added side forces. This is based on the instructions given here by the forum member drrbradford at CFD-Online.

This git repository was brought to you by Bruno Santos (wyldckat@github working at blueCAPE Lda).

How to get+build forceDirCoeffs

These instructions are for OpenFOAM 2.1.x:

For getting and building from git:

git clone git://github.com/wyldckat/forceDirCoeffs.git
cd forceDirCoeffs
git checkout of21x
wmake libso forceDirCoeffs

For getting and building from zip:

wget "https://github.com/wyldckat/forceDirCoeffs/archive/of21x.zip" -O forceDirCoeffs.zip
unzip forceDirCoeffs.zip
cd forceDirCoeffs-of21x
wmake libso forceDirCoeffs

There is port for OpenFOAM 2.2.x as well! Simply replace on the instructions above of21x for of22x.

How to use it

The idea is that you should add the following line to the "controlDict" file:

libs (libforceDirCoeffs.so);

In case you already have a line that starts with "libs", then add the library name to the list, for example: If you have this:

libs (
    libforces.so
);

It becomes this:

libs (
    libforces.so
    libforceDirCoeffs.so
);
