Foam::geometricZeroField
|
|
|
|
Description
|
|
A class representing the concept of a GeometricField of 1 used to avoid
|
|
unnecessary manipulations for objects which are known to be zero at
|
|
compile-time.
|
|
|
|
Used for example as the density argument to a function written for
|
|
compressible to be used for incompressible flow.
