how to apply calculated type of primitive patch field. i have a relation between p and v at that boundary (patch) , say p=constant * v. so how should i write p and v boundary condition for that patch.
is there anybody who can help me..............

I think one way to solve your problem was the following. (But its only a suggest and surely not the only one)
1. set boundaryType for U to zeroGradient
2. set boundaryType for p to fixedValue
3. solve Eqns
4. set value on boundary of p to C*U
5. repeat steps 3-4 and hope for convergence
Does anyone know about a more elegant solution?
