Source and Source coefficient
I feel that source and source coeffcient have not been documented properly in CFX. I have a doubt and I will take an example to explain that.
We know that a source "S" when linearized takes the form S = Sc+Sp.phi where phi is the variable being solved and Sp = dS_by_dphi (partial derivative). This should be negative. Sc = S - (Sp*phi)
For example, consider S = - (B * phi*phi)where phi is the variable and B is a constant. According to CFX
Is source = (B*phi*phi) and source coefficient = (-2*B*phi)
source = -(B*phi*phi) and source coeffcient = (-2*B*phi)
Finally I want to ask if source in CFX terms means S or Sc as per above discussion. Please clarify.
