The polyTopoChangeMap is the map specifically relating to polyMesh topological
changes generated by polyTopoChange and used to update and map mesh related
types and fields following the topo-change.
setTimeStep is now compatible with a 'writeControl adjustableRunTime;'
setting in the systemControlDict. If 'adjustableRunTime' is selected
then the time-step values set by this function object will not be
exactly as specified, but write intervals will be matched exactly.
All function object time adjustment is now done during the execute
methods, so the specific setTimeStep hooks have been removed.
This avoids attempting to write temporary fields before they have been created.
The executeAtStart can be set to 'yes' in the writeObjects dictionary or the
functions
{
#includeFunc writeObjects(executeAtStart = yes, <field1>, <field2>...)
}
Rather than being tied to the Time class the dlLibraryTable libs is now a global
variable in the Foam namespace which is accessable by any class needing to load
dynamic libraries, in particular argList, Time and codeStream.
This change formalises the usage of the "log" keyword in function
objects. By default, logging to stdout is activated when running
"postProcess" or "<solver> -postProcess", and deactivated when a
function is being executed as part of a run.
This behaviour can now be overridden in the function object dictionary
when operating in either mode.
By default most functionObjects now execute and write at the start-time except
those that perform averaging (fieldAverage, dsmcFields) which cannot be executed
until the end of the first time-step. There is also a new optional
functionObject dictionary entry "executeAtStart" which defaults to true but can
be set false if the execution and results of the functionObject are not required
or appropriate at the start-time.
A result of this change is that time logs of forces, sampling etc. now include a
values for time 0.
The logic governing function objects' ability to change the time-step
has been modified so that it is compatible with the time-step adjustment
done in the Time class. The behaviour has been split into a method which
sets the step directly, and another which moidifies the time until the
next write operation (i.e., the time that the solver "aims" for).
This fixes an issue where the adjustments in Time and the function
objects interfere and cause the time step to decrease exponentially down
to machine precision. It also means that the set-time-step function
object now does not break the adjustable run-time setting.
This resolves bug report https://bugs.openfoam.org/view.php?id=2820
Time: call functionObject 'execute()' and 'end()' for last time-step
Now the operation of functionObject 'end()' call is consistent between running and post-processing
the equivalent functionality is provided by the writeRegisteredObject
functionObject in a MUCH simpler, easier and extensible manner.
functionObject: Removed the now redundant 'timeSet' function.
This changes simplifies the specification of functionObjects in
controlDict and is consistent with the 'libs' option in controlDict to
load special solver libraries.
Support for the old 'functionObjectLibs' name is supported for backward compatibility.
- Avoids the need for the 'OutputFilterFunctionObject' wrapper
- Time-control for execution and writing is now provided by the
'timeControlFunctionObject' which instantiates the processing
'functionObject' and controls its operation.
- Alternative time-control functionObjects can now be written and
selected at run-time without the need to compile wrapped version of
EVERY existing functionObject which would have been required in the
old structure.
- The separation of 'execute' and 'write' functions is now formalized in the
'functionObject' base-class and all derived classes implement the
two functions.
- Unnecessary implementations of functions with appropriate defaults
in the 'functionObject' base-class have been removed reducing
clutter and simplifying implementation of new functionObjects.
- The 'coded' 'functionObject' has also been updated, simplified and tested.
- Further simplification is now possible by creating some general
intermediate classes derived from 'functionObject'.
