Summary0000702: dynamicAlphaContactAngle code does not calculate pinning force
DescriptionI would expect that when using a dynamic contact angle model there would be an expression for the contact line force like:

F = γ (cos θ - cos θe)

where θe is the equilibrium contact angle and θ is the actual contact angle. However, this is not there in the dynamicAlphaContactAngle.C file and therefor it is not possible to do, for example, simulations on critical-inclination for a droplet on a plate.

The current model is based on a fit to experimental data for a particular problem; if you would like to propose an alternative formulation feel free to sumbit the code for consideration.

Looking through the code is seems I will need to add a force term in the file applications/solvers/multiphase/interFoam/UEqn.H . Would you have an idea how to define the force in such a way that it will only act on the contact line of the solid, gas, an liquid interface?
