The angle might change and the is what a lot of scientist are claiming: one does not need a dynamic contact angle if one does use very fine mesh and shaprly convect the interface.


The same amount of researchers claim that one does require a dynamic contact angle to avoid any wrong capturing of contact line.


 


Again I still wonder if storing the gradients of the volume fraction and doing the dot product with face normal will return the same angle or a changing angle.


 


Again all above assuming you have a proper resolution.


The wall adhesion is posing a boundary for the free surface and not a boundary for the wall itself
