  Equilibrium contact angle of liquid drops over horizontal surfaces has been
modeled using Smoothed Particle Hydrodynamics (SPH). The model is capable of
accurate implementation of contact angles to stationary and moving contact
lines. In this scheme, the desired value for stationary or dynamic contact
angle is used to correct the profile near the triple point. This is achieved by
correcting the surface normals near the contact line and also interpolating the
drop profile into the boundaries. Simulations show that a close match to the
chosen contact angle values can be achieved for both stationary and moving
contact lines. This technique has proven to reduce the amount of nonphysical
shear stresses near the triple point and to enhance the convergence
characteristics of the solver.
