27 Class
28  Foam::zeroFieldField
29 
30 Description
31  A class representing the concept of a field of zeroFields used to
32  avoid unnecessary manipulations for objects which are known to be zero at
33  compile-time.
34 
35  Used for example as the density argument to a function written for
36  compressible to be used for incompressible flow.
