Hello,


What Fluent solver is adjusting is the local curvature one cell away from the wall based on the prescribed contact angle when wall adhesion is activated. The combination of contact angle with the estimated surface normal changes the local curvature. In this case, the contact angle specified should be the equilibrium contact angle.


To read more about this, please refer to the Fluent Theory guide (section 18.3.9.2 - Wall Adhesion). Here is the link: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v201/en/flu_th/flu_th_vof_surf_tens.html


If you are looking for a truly dynamic contact angle, you should be relying on a UDF.

I hope this clarifies your question.


Thank you.
