Example 94: Gas mixing in an asymmetric conducting airway/LPM model


The comfile run by this example is as follows:

#Example_94  Gas mixing in an asymmetric conducting airway/LPM model
#This example simulates mixing of sulpherhexafloride with nitrogen
#in a full lung model.  The conducting airways are asymmetric, grown
#as described in example 93.  Each terminal conducting airway branch is
#attached to a lumped parameter model of the acinus as described in 
#example 92.
