These functions calculate the specie-flux and write it as a
surfaceScalarField called 'specie<Type>Flux(<specieName>)'. There are
three such functions; specieAdvectiveFlux and specieDiffusiveFlux return
the advective and diffusive parts of the flux, respectively, and
specieFlux returns the total combined flux.
Example of function object specification:
specieFlux
{
type specieFlux; // specieAdvectiveFlux, specieDiffusiveFlux
libs ("libfieldFunctionObjects.so");
field NH3;
}
Or, using the standard configuration:
#includeFunc specieFlux(NH3)
Whilst the cell values of non-solved species do not change, the boundary
values might, and correcting them is necessary for certain
post-processing operations to produce sensible results.
Various minor changes to tutorial scripts. In particular, ensuring that
they all change to the containing directory so that batches of tutorials
can be run easily from the root of the installation.
The option to specify rpm as the keyword is deprecated in favour of
specifying omega with a unit conversion from [rpm]. The documentation
for the omega input classes have been updated to reflect this.
for input parameters in OpenFOAM, e.g.
+ to list available units:
foamUnits -list
+ to provide information about the [mm] unit:
foamUnits mm
+ to provide information about the [thermalConductivity] dimensions:
foamUnits -dimension thermalConductivity
+ to provide information about all units:
foamUnits -all
+ to provide information about all dimensions:
foamUnits -all -dimension
Due to rounding to the nearest value it is possible for the updated time name to
predate the previous time name after a precision change, for example as a
consequence of a sudden reduction in time-step. This is not an error and should
not cause the run to stop but the user is warned about the temporary anomaly in
the printing of time.
The fvModels directory has been reorganised into separate libraries to make it
easier to add and maintain new complex models such as the propellerDisk.

Some functions have been removed from this tutorial in order to simplify
the setup and permit its usage as a minimal example. The functions have
been moved to similar incompressibleFluid tutorials in order to ensure
that the test loop continues to confirm that the functions execute
successfully.
