In most boundary conditions, fvOptions etc. required and optional fields
to be looked-up from the objectRegistry are selected by setting the
keyword corresponding to the standard field name in the BC etc. to the
appropriate name in the objectRegistry. Usually a default is provided
with sets the field name to the keyword name, e.g. in the
totalPressureFvPatchScalarField the velocity is selected by setting the
keyword 'U' to the appropriate name which defaults to 'U':
Property | Description | Required | Default value
U | velocity field name | no | U
phi | flux field name | no | phi
.
.
.
However, in some BCs and functionObjects and many fvOptions another
convention is used in which the field name keyword is appended by 'Name'
e.g.
Property | Description | Required | Default value
pName | pressure field name | no | p
UName | velocity field name | no | U
This difference in convention is unnecessary and confusing, hinders code
and dictionary reuse and complicates code maintenance. In this commit
the appended 'Name' is removed from the field selection keywords
standardizing OpenFOAM on the first convention above.
Generally fields and objects are selected using the 'field[s]' and
'object[s]' keywords but this was not consistent between all
functionObject, fvOptions etc. and now fixed by applying the following
renaming:
fieldName -> field
fieldNames -> fields
objectName -> object
objectNames -> objects
Updated and simplified 'div', 'grad' and 'mag' functionObjects by deriving from 'fieldExpression'.
Corrected the handling of cached gradients in 'grad'.
instead of removing them. Now done similar to 23x:
- in 'removing unreachable parts of mesh' keep regions unset (so they get removed)
- in final zoning set to background region
See Gitlab #66.
the equivalent functionality is provided by the writeRegisteredObject
functionObject in a MUCH simpler, easier and extensible manner.
functionObject: Removed the now redundant 'timeSet' function.
codedFunctionObject: Added the "codeWrite" entry
for the "write" function for consistency.
The previous method of using the "code" entry for the "write"
function was inconsistent and very confusing.
