      TDACChemistryModel: New chemistry model providing Tabulation of Dynamic Adaptive Chemistry · 1d572696
      Henry Weller authored
      Provides efficient integration of complex laminar reaction chemistry,
      combining the advantages of automatic dynamic specie and reaction
      reduction with ISAT (in situ adaptive tabulation).  The advantages grow
      as the complexity of the chemistry increases.

      Two tutorial cases are currently provided:
          + tutorials/combustion/chemFoam/ic8h18_TDAC
          + tutorials/combustion/reactingFoam/laminar/counterFlowFlame2D_GRI_TDAC
      
      the first of which clearly demonstrates the advantage of dynamic
      adaptive chemistry providing ~10x speedup,
      
      the second demonstrates ISAT on the modest complex GRI mechanisms for
      methane combustion, providing a speedup of ~4x.
      
      More tutorials demonstrating TDAC on more complex mechanisms and cases
      will be provided soon in addition to documentation for the operation and
      settings of TDAC.  Also further updates to the TDAC code to improve
      consistency and integration with the rest of OpenFOAM and further
      optimize operation can be expected.
      
      Original code providing all algorithms for chemistry reduction and
      tabulation contributed by Francesco Contino, Tommaso Lucchini, Gianluca
      D’Errico, Hervé Jeanmart, Nicolas Bourgeois and Stéphane Backaert.
      
      Implementation updated, optimized and integrated into OpenFOAM-dev by
      Henry G. Weller, CFD Direct Ltd with the help of Francesco Contino.

      ODESolvers: Add support for efficient ODE solver resizing · a5d73747
      Henry Weller authored
      Note: this reuses the existing storage rather than costly reallocation
      which requires the initial allocation to be sufficient for the largest
      size the ODE system might have.  Attempt to set a size larger than the
      initial size is a fatal error.
