This model demonstrates the use of trace substances that are added
to a volume of air. The source is a step function of 2 kg/s
CO2 from t=0 second to t=0.5 second. The
sensors C and C1 measure the same
concentration that initially increases and then remains constant as
there is no flow through the volumes vol and
vol1. The sensors C2 and C3
first meaure an increase in concentration, which then decays to
zero as there is a mass flow rate with zero CO2 from the
source bou to the sink sin.

Configured the sensor parameter to suppress the warning about being
a one-port connection.
This is for IBPSA,
#1857.
- November 27, 2013 by Michael Wetter:
Added pressure boundary condition to model. This is required for
the new air model, which is incompressible. Otherwise, there will
be no pressure reference in the system.

Simplified example.

Changed the initialization of the medium volumes from free initial
conditions to
Modelica.Fluid.Types.Dynamics.FixedInitial. This was
required for vol and vol1 to have the
same computations for the initial states.

First implementation.
