@@ -993,6 +993,10 @@ Residual TC is also modeled by a polynominal.
 At the critical point TC becomes infinite; TC is enhanced for a large region around the critical point.
 The critical enhancement can be described by various alternative approaches.
 Here, the simplified approach as suggested by Olchowy and Sengers is implemented.

 At the critical point and a small region around the critical point, the viscosity is enhanced. 
 As this critical enhancement is small, it is neglected here.
