24 Class
25  Foam::functionObjects::flowType
26 
27 Description
28  Calculates and writes the flowType of a velocity field.
29 
30  The flow type parameter is obtained according to the following equation:
31  \verbatim
32  |D| - |Omega|
33  lambda = -------------
34  |D| + |Omega|
35 
36  -1 = rotational flow
37  0 = simple shear flow
38  1 = planar extensional flow
39  \endverbatim
