Hello Everyone,

If i have a pipe flow and I want to impose a slip condition at the wall varying with local tube radius, cause the tube is not straight but it's radius is different from point to point. How can I insert R in this expression :

Wall
{
type codedFixedValue;
value uniform (0 0 0);
redirectType rampedFixedValue;
code
#{
vector (0, 0 , f(R)*DUz/Dy);
#};
}



Thank you very much
