The old separate incompressible and compressible libraries have been removed. Most of the commonly used RANS and LES models have been upgraded to the new framework but there are a few missing which will be added over the next few days, in particular the realizable k-epsilon model. Some of the less common incompressible RANS models have been introduced into the new library instantiated for incompressible flow only. If they prove to be generally useful they can be templated for compressible and multiphase application. The Spalart-Allmaras DDES and IDDES models have been thoroughly debugged, removing serious errors concerning the use of S rather than Omega. The compressible instances of the models have been augmented by a simple backward-compatible eddyDiffusivity model for thermal transport based on alphat and alphaEff. This will be replaced with a separate run-time selectable thermal transport model framework in a few weeks. For simplicity and ease of maintenance and further development the turbulent transport and wall modeling is based on nut/nuEff rather than mut/muEff for compressible models so that all forms of turbulence models can use the same wall-functions and other BCs. All turbulence model selection made in the constant/turbulenceProperties dictionary with RAS and LES as sub-dictionaries rather than in separate files which added huge complexity for multiphase. All tutorials have been updated so study the changes and update your own cases by comparison with similar cases provided. Sorry for the inconvenience in the break in backward-compatibility but this update to the turbulence modeling is an essential step in the future of OpenFOAM to allow more models to be added and maintained for a wider range of cases and physics. Over the next weeks and months more turbulence models will be added of single and multiphase flow, more additional sub-models and further development and testing of existing models. I hope this brings benefits to all OpenFOAM users. Henry G. Weller

execFlowFunctionObjects
|
|
|
|
Description
|
|
Execute the set of functionObjects specified in the selected dictionary
|
|
(which defaults to system/controlDict) for the selected set of times.
|
|
Alternative dictionaries should be placed in the system/ directory.
|
|
|
|
The flow (p-U) and optionally turbulence fields are available for the
|
|
function objects to operate on allowing forces and other related properties
|
|
to be calculated in addition to cutting planes etc.
