Hi Foamers;

I have a rather basic question. I am dealing with two phase flows using the interFOAM solver. I try to implement the boundary condition for the contact angle at the top and bottom layers of my rectangular domain.

I use the following boundary condition:
top {
type constantAlphaContactAngle;
limit gradient;
theta0 0;
value uniform 1;
}

I am curious to know what does the value uniform 1 mean in this case? I even changed the value to uniform 0 and I have the same set of results.

I would be happy if anyone could clarify this.

Thanks.

Default value is the fixed angle of contact to the solid surface.

Sorry guys;

it was so easy!! The value over there is for the contact angle. 0 - 180 are valid. 0 is not considering any contact angle effects and any value of alpha depends on the condition for your run.

Could be useful for any others. Sorry to bother you!!
