charles4allme Member Join Date: Feb 2018 Posts: 91 Rep Power: 8	Hello, I want to add a source term to the momentum equation (UEqn). I understand that the source term is usually contained in the matrix UEqn.H but in this case I would like to develop a source term that acts as a constrain equation. The constrain equation is given as: Code: $\Phi$ U = Q where U is the velocity and Q is the flow rate. I will like to develop a matrix coefficient for $\Phi$ and I am wondering how I will go about doing this. The matrix I believe would contain the area of the patch at the boundary. I appreciate any assistance with the question. Regards charles.
