Chemistry integration occurs over the simulation timestep, and should therefore be initialised with old time properties. This is now the case. This means that outer iteration of the chemistry within a timestep is now correct. In addition, the laminar combustion model (and derivations) has a new flag which prevents it from being corrected more than once per timestep. This flag is true by default, as outer iteration of a typical reaction system is expensive and provides limited benefit.

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
