 Description: Stream level options
              0=Mass Balance
              1=Mass, Mole, and Energy Balances

STREAM_LEVEL controls the amount of detailed contained in flowsheet models through OBJECT declarations. At the basic level (0), only mass balance equations are solved. Variables for each stream are mass flow rate and mass fractions of all species declared in the COMPOUNDS section of the model. The last mass fraction is automatically set to make the summation equal to 1.0. At more the more advanced level (1), mole and energy balances are added. The higher stream level adds temperature, pressure, enthalpy, mole fractions, volumetric flow, density, and concentration.
