Best way to measure the contact angle in-situ in Fluent?
For reasons specific to my application, I don't want to set a contact angle boundary condition. However, I would like to measure the contact angle during my simulation. What is the best way to do this? Currently, I'm looking at the gradient for the cell at the boundary that has a C_VOF value closest to 0.5 and extracting the contact angle from that. However, this doesn't seem like a super accurate way to do it since it seem like adjacent cells have quite different values for the gradient.
If there simply a command or something I can use to calculate it?
