      INT: Integration of isoAdvector and supporting material · a6ef8b90
      Andrew Heather authored
      Community contribution from Johan Roenby, DHI
      
      IsoAdvector is a geometric Volume-of-Fluid method for advection of a
      sharp interface between two incompressible fluids. It works on both
      structured and unstructured meshes with no requirements on cell shapes.
      IsoAdvector is as an alternative choice for the interface compression
      treatment with the MULES limiter implemented in the interFoam family
      of solvers.
      
      The isoAdvector concept and code was developed at DHI and was funded
      by a Sapere Aude postdoc grant to Johan Roenby from The Danish Council
      for Independent Research | Technology and Production Sciences (Grant-ID:
      DFF - 1337-00118B - FTP).
      Co-funding is also provided by the GTS grant to DHI from the Danish
      Agency for Science, Technology and Innovation.
      
      The ideas behind and performance of the isoAdvector scheme is

      ENH: overset: Initial release of overset capability. · fd665b4a
      mattijs authored
      Adds overset discretisation to selected physics:
      - diffusion : overLaplacianDyMFoam
      - incompressible steady : overSimpleFoam
      - incompressible transient : overPimpleDyMFoam
      - compressible transient: overRhoPimpleDyMFoam
      - two-phase VOF: overInterDyMFoam
      
      The overset method chosen is a parallel, fully implicit implementation
      whereby the interpolation (from donor to acceptor) is inserted as an
      adapted discretisation on the donor cells, such that the resulting matrix
      can be solved using the standard linear solvers.
      
      Above solvers come with a set of tutorials, showing how to create and set-up
      simple simulations from scratch.

      The "<type>Coeffs" sub-dictionary is now optional for most model parameters · 5c518365
      Henry Weller authored
      except turbulence and lagrangian which will also be updated shortly.
      
      For example in the nonNewtonianIcoFoam offsetCylinder tutorial the viscosity
      model coefficients may be specified in the corresponding "<type>Coeffs"
      sub-dictionary:
      
      transportModel  CrossPowerLaw;
      
      CrossPowerLawCoeffs
      {
          nu0         [0 2 -1 0 0 0 0]  0.01;
          nuInf       [0 2 -1 0 0 0 0]  10;
          m           [0 0 1 0 0 0 0]   0.4;
          n           [0 0 0 0 0 0 0]   3;
      }
      
      BirdCarreauCoeffs
      {
          nu0         [0 2 -1 0 0 0 0]  1e-06;
          nuInf       [0 2 -1 0 0 0 0]  1e-06;
          k           [0 0 1 0 0 0 0]   0;
          n           [0 0 0 0 0 0 0]   1;
      }
      
      which allows a quick change between models, or using the simpler
      
      transportModel  CrossPowerLaw;
      
      nu0         [0 2 -1 0 0 0 0]  0.01;
      nuInf       [0 2 -1 0 0 0 0]  10;
      m           [0 0 1 0 0 0 0]   0.4;
      n           [0 0 0 0 0 0 0]   3;
      
      if quick switching between models is not required.
      
      To support this more convenient parameter specification the inconsistent
      specification of seedSampleSet in the streamLine and wallBoundedStreamLine
      functionObjects had to be corrected from
      
          // Seeding method.
          seedSampleSet   uniform;  //cloud; //triSurfaceMeshPointSet;
      
          uniformCoeffs
          {
              type        uniform;
              axis        x;  //distance;
      
              // Note: tracks slightly offset so as not to be on a face
              start       (-1.001 -0.05 0.0011);
              end         (-1.001 -0.05 1.0011);
              nPoints     20;
          }
      
      to the simpler
      
          // Seeding method.
          seedSampleSet
          {
              type        uniform;
              axis        x;  //distance;
      
              // Note: tracks slightly offset so as not to be on a face
              start       (-1.001 -0.05 0.0011);
              end         (-1.001 -0.05 1.0011);
              nPoints     20;
          }
      
      which also support the "<type>Coeffs" form
      
          // Seeding method.
          seedSampleSet
          {
              type        uniform;
      
              uniformCoeffs
              {

                  start       (-1.001 -0.05 0.0011);

      thermophysicalProperties: New base-class for liquidProperties and in the future gasProperties · d2be6454
      Henry Weller authored
      Description
          Base-class for thermophysical properties of solids, liquids and gases
          providing an interface compatible with the templated thermodynamics
          packages.
      
      liquidProperties, solidProperties and thermophysicalFunction libraries have been
      combined with the new thermophysicalProperties class into a single
      thermophysicalProperties library to simplify compilation and linkage of models,
      libraries and applications dependent on these classes.

      thermophysicalModels: Changed specie thermodynamics from mole to mass basis · c52e4b58
      Henry Weller authored
      The fundamental properties provided by the specie class hierarchy were
      mole-based, i.e. provide the properties per mole whereas the fundamental
      properties provided by the liquidProperties and solidProperties classes are
      mass-based, i.e. per unit mass.  This inconsistency made it impossible to
      instantiate the thermodynamics packages (rhoThermo, psiThermo) used by the FV
      transport solvers on liquidProperties.  In order to combine VoF with film and/or
      Lagrangian models it is essential that the physical propertied of the three
      representations of the liquid are consistent which means that it is necessary to
      instantiate the thermodynamics packages on liquidProperties.  This requires
      either liquidProperties to be rewritten mole-based or the specie classes to be
      rewritten mass-based.  Given that most of OpenFOAM solvers operate
      mass-based (solve for mass-fractions and provide mass-fractions to sub-models it
      is more consistent and efficient if the low-level thermodynamics is also
      mass-based.
      
      This commit includes all of the changes necessary for all of the thermodynamics
      in OpenFOAM to operate mass-based and supports the instantiation of
      thermodynamics packages on liquidProperties.
      
      Note that most users, developers and contributors to OpenFOAM will not notice
      any difference in the operation of the code except that the confusing
      
          nMoles     1;
      
      entries in the thermophysicalProperties files are no longer needed or used and
      have been removed in this commet.  The only substantial change to the internals
      is that species thermodynamics are now "mixed" with mass rather than mole
      fractions.  This is more convenient except for defining reaction equilibrium
      thermodynamics for which the molar rather than mass composition is usually know.
      The consequence of this can be seen in the adiabaticFlameT, equilibriumCO and
      equilibriumFlameT utilities in which the species thermodynamics are
      pre-multiplied by their molecular mass to effectively convert them to mole-basis
      to simplify the definition of the reaction equilibrium thermodynamics, e.g. in
      equilibriumCO
      
          // Reactants (mole-based)
          thermo FUEL(thermoData.subDict(fuelName)); FUEL *= FUEL.W();
      
          // Oxidant (mole-based)
          thermo O2(thermoData.subDict("O2")); O2 *= O2.W();
          thermo N2(thermoData.subDict("N2")); N2 *= N2.W();
      
          // Intermediates (mole-based)
          thermo H2(thermoData.subDict("H2")); H2 *= H2.W();
      
          // Products (mole-based)
          thermo CO2(thermoData.subDict("CO2")); CO2 *= CO2.W();
          thermo H2O(thermoData.subDict("H2O")); H2O *= H2O.W();
          thermo CO(thermoData.subDict("CO")); CO *= CO.W();
      
          // Product dissociation reactions
      
          thermo CO2BreakUp
          (
              CO2 == CO + 0.5*O2
          );
      
          thermo H2OBreakUp
          (
              H2O == H2 + 0.5*O2
          );

      thermodynamic at https://bugs.openfoam.org

      compressibleInterFoam: Completed LTS and semi-implicit MULES support · b167c95f

      Now the interFoam and compressibleInterFoam families of solvers use the same
      alphaEqn formulation and supporting all of the MULES options without
      code-duplication.
      
      The semi-implicit MULES support allows running with significantly larger
      time-steps but this does reduce the interface sharpness.
