Detailed Description

Abstract base class for two-phase alphaContactAngle boundary conditions.

Derived classes must implement the theta() function which returns the wall contact angle field.

The essential entry "limit" controls the gradient of alpha1 on the wall:

none - Calculate the gradient from the contact-angle without limiter
gradient - Limit the wall-gradient such that alpha1 remains bounded on the wall
alpha - Bound the calculated alpha1 on the wall
zeroGradient - Set the gradient of alpha1 to 0 on the wall, i.e. reproduce previous behaviour, the pressure BCs can be left as before.

Note that if any of the first three options are used the boundary condition on p_rgh must set to guarantee that the flux is corrected to be zero at the wall e.g.:

<patchName>
{
    type            alphaContactAngle;
    limit           none;
}
