Dynamic Contact Angle UDF in Fluent

codyn · April 16, 2009, 07:08

Hi, I would like to see the effect of dynamic contact angle on the VOF model. Can somebody share a UDF model code for getting me started on this. I appreciate your help. Thanks, codyn.

Hello,
I am also trying to write a UDF for finding dynamic contact angle using Blake's approach. As per this approach, I need to get contact line velocity from the simulation at each time step and use that to get dynamic contact angle. Can anybody guide me how to get the contact line velocity at adjacent cells to the wall and on the water-air interface?
Thanks in advance !
