     Not specified: default used.
     Fully specified: rhoMax          rhoMax [ 1 -3 0 0 0 ] 2.0;
     Without name:    rhoMax          [ 1 -3 0 0 0 ] 2.0;
     Value only:      rhoMax          2.0;

turbulenceModels/LES/dynamicLagrangian: Added the Lagrangian averaged form of the dynamic Smagorinsky eddy-viscosity SGS model for LES

potentialFoam: Solve for velocity potential named Phi rather than using the pressure field for this purpose

The Phi field is read if available otherwise created automatically with
boundary conditions obtained automatically from the pressure field if
available (with optional name) otherwise inferred from the velocity
field.  Phi Laplacian scheme and solver specification are required.  See
tutorials for examples.

tutorials/heatTransfer/chtMultiRegionSimpleFoam/heatExchanger/system/air/topoSetDict.1: further correction to avoid duplicate registration

GeometricField: Do not transfer registration of a GeometricField to a copy unless it is being transferred from a tmp
This avoids loosing the registration of non-tmp fields

Use interFoam with fvOptions
