Default Contact angle in OpenFoam with fixedfluxpressure

Eller_OF is on a distinguished road

I have a question on how to change the contact angle using the fixedFluxPressure BC on the Walls. The simulation has been sent to me and I am supposed to only change the angle from now (Iíve been told) 45 degrees to 70 degrees.

Usually I would use

type constantAlphaContactAngle;
theta0 45;
limit gradient;
value uniform 0;

In 0/U folder and then just change the theta0.

But the simulation i work with has a

type fixedFluxPressure;

So now i am unfortunately unsure about what to do.

To sum up: The simulation currently uses contact angle = 45 degrees and I cannot find where this has been set.

So if anyone has an idea i would be super thankful.

(Using interfoam)
