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.
Class
Foam::fv::propellerDisk
Description
Disk momentum source which approximates a propeller based on a given
propeller curve.

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.
This update allows Zoltan to be used by snappyHexMesh to redistribute the mesh
after refinement and sub-setting even if some processors loose all their cells
in the process.
Poly-mesh mesh objects are now in a subdirectory of the polyMesh
directory. The cpuLoad object has been made a polyMesh object, rather
than an fvMesh object, in order to remove the dependence on the finite
volume library. This has, in turn, removed the base lagrangian library's
dependence on finite volume.
Note that this fvModel provides the missing conservative redistribution term for
the viscous heating, the main part of the viscous heating effect is provided by
the inclusion of the kinetic energy equation in the internal energy equation to
form the total energy equation.
This enables the correct solution of FV-motion fields during mesh
updates when the mesh is in an unstitched state.

ParMETIS cannot handle processors containing no cells, a fatal error is
generated, to work around this limitation a special communicator is created
containing only those processors which have cells and ParMETIS called only for
those processors.
This update allows ParMETIS to be used by snappyHexMesh to redistribute the mesh
after refinement and sub-setting even if some processors loose all their cells
in the process.
