Alpha contact angle boundaries are now specified in the following way
for multiphase solvers (i.e., multiphaseInterFoam,
compressibleMultiphaseInterFoam, and multiphaseEulerFoam):
boundaryField
{
wall
{
type alphaContactAngle;
contactAngleProperties
{
water
{
// Constant contact angle
theta0 90;
}
oil
{
// Dynamic contact angle
theta0 90;
uTheta 1;
thetaA 125;
thetaR 85;
}
}
value uniform 0;
}
}
All solvers now share the same implementation of the alphaContactAngle
boundary condition and the contact angle correction algorithm.
If alpha contact angle boundary conditions are used they must be
specified for all phases or an error will result. The consistency of the
input will also be checked. The angles given for water in the alpha.air
file must be 180 degrees minus the angles given for air in the
alpha.water file.
