      We created a geometry filled with multiple hydrophobic spheres inside a cylindrical tube and are flowing water/acetonitrile at a constant composition. We define hydrophobicity by setting the contact angle of the spheres to 120 degrees, but when we ran simulations, an excess water layer still flowed near the spheres. Do you have any suggestions for improvement? Also, is defining hydrophobicity solely by the contact angle insufficient to convey the property of being hydrophobic?
