  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.
