Foam::zeroField
|
|
|
|
Description
|
|
A class representing the concept of a field of 0 used to avoid unnecessary
|
|
manipulations for objects which are known to be zero at compile-time.
|
|
|
|
Used for example as the argument to a function in which certain terms are
|
|
optional, see source terms in the MULES solvers.
