accessing value of contact angle
 

Hey Guys,

with hoping that my problem fits into this category, was wondering if anyone could help with accessing and changing the value of contact angle for a certain patchID?

in other words to break it down, I wanna change the value of contact angle within the main code block (not where the alpha property is defined) to another value for a certain patch (let's call it wall) within a certain region (like a box) of the mesh (not everywhere)?

since the BC I'm dealing with is a alphaContactAngleFvPatchScalarField, was wondering if I can use setFields to define a region (box in this case) and apply this change (if so please specify how I can do this), and if not any other suggestion?

any help is highly appreciated!
