Linearizing the expression of source term

      Suppose I have a source term that is nonlinear. 

      This source term is a function of saturation

      source = f(S) = s^(-3) 

      if i write the expression in fluent

      should i linearize this expression for writing the source term? (using fluent expressions)

      There's not anywhere to plug in the linearised term if you use Expressions, only in the UDF approach.
