Free Open Source CFD!

The 'Partial derivative logo' is also used for the 7th OpenFOAM® Workshop: in the context of community-driven conferences, workshops and meetings around the Open Source CFD platform OpenFOAM®, we additionally use the Greek letter ι (iota) after the 'Partial derivative logo', appreviating open and  free '∂ιscussion'. This, in our understanding, is a prerequisite of community-driven Open Source CFD Software development, which we want to foster by organizing the 7th OpenFOAM® Workshop.
