For some systems the thermal coupling between the solid and fluid regions
dominates overall convergence and it may be beneficial to sub-iterate over the
thermal system as the energy solution is cheaper than the pressure-velocity
system. To test this the new optional nEcorr entry in system/fvSolution is
provided which defaults to 1, e.g.
PIMPLE
{
nOuterCorrectors 1;
nEcorr 2;
}
If this proves useful it could be extended and improved by adding convergence
controls.
Note that the solution of the solid regions is now before the fluid regions as
it make more sense if solid regions are sources or sinks of heat to solve them
before the fluid.

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.
