The new flexible and extensible modular solvers structure already provides most
of the simulation functionality needed for single phase, multiphase,
multicomponent etc. fluid flow problems as well as a very effective method of
combining these with solid heat transfer, solid stress, surface film to solve
complex multi-region, multi-physics problems and are now the primary mechanism
for the further development of OpenFOAM simulation capability in future. To
emphasis this for both users and developers the applications/solvers directory
has been separated into applications/modules containing all the solver modules:
├── modules
│ ├── compressibleMultiphaseVoF
│ ├── compressibleVoF
│ ├── film
│ ├── fluid
│ ├── fluidSolver
│ ├── functions
│ ├── incompressibleDenseParticleFluid
│ ├── incompressibleDriftFlux

│ ├── multiphaseVoFSolver
│ ├── shockFluid
│ ├── solid
│ ├── solidDisplacement
│ ├── twoPhaseSolver
│ ├── twoPhaseVoFSolver
│ ├── VoFSolver
│ └── XiFluid
applications/solvers containing the foamRun and foamMultiRun solver applications
which instantiate and execute the chosen solver modules and also standalone
solver applications for special initialisation and test activities:
├── solvers
│ ├── boundaryFoam
│ ├── chemFoam
│ ├── foamMultiRun
│ ├── foamRun
│ └── potentialFoam
and applications/legacy containing legacy solver applications which are not
currently being actively developed but the functionality of which will be merged
into the solver modules or form the basis of new solver modules as the need
arises:
├── legacy

│ │ ├── financialFoam
│ │ └── laplacianFoam
│ ├── combustion
│ │ └── PDRFoam

│ │ ├── icoFoam
│ │ ├── porousSimpleFoam
│ │ └── shallowWaterFoam
│ └── lagrangian
│ ├── dsmcFoam
│ ├── mdEquilibrationFoam
│ └── mdFoam
Correspondingly the tutorials directory structure has been reorganised with the
modular solver directories at the top level with names that make it easier for
users to find example cases relating to their particular requirements and a
legacy sub-directory containing cases corresponding to the legacy solver
applications listed above:

Notes:
|
|
The reference gives parameters in a unit system of cm-sec-mole-kcal-Kelvin,
|
|
whilst OpenFOAM uses m-sec-kmol-J-Kelvin, both the pre-exponential factors
|
|
and the activation temperature/energy require unit conversion.
|
|
|
|
The mechanism used is set 3 from table 2. This should be the most accurate
|
|
single-step methane mechanism without any negative exponents. Set 2 is not
|
|
usable because the negative exponent on the methane concentration causes
|
|
divergence in regions without any fuel.
