With this option the specific heat at constant pressure and the dynamic viscosity of a gas or liquid can be defined. These properties are required for fluid dynamic network calculations. They can be temperature dependent.
Example: *FLUID CONSTANTS 1.032E9,71.1E-13,100.
defines the specific heat and dynamic viscosity for air at 100 in a unit system using N, mm, s and K: mms K and N s mm.
