For multi-region cases the default location of blockMeshDict is now system/<region name>
If the blockMeshDict is not found in system then the constant directory
is also checked providing backward-compatibility
Command-line option handling:
+ If -all specified or no refineMeshDict exists or, refine all cells
+ If -dict <file> specified refine according to <file>
+ If refineMeshDict exists refine according to refineMeshDict
When the refinement or all cells is selected apply 3D refinement for 3D
cases and 2D refinement for 2D cases.

potentialFoam: Added new method to estimate the static pressure field from the velocity
Uses a form of the Euler equation in which only variation along the streamlines is considered

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.
This allows checkMesh and other mesh manipulation utilities to operate
on the mesh without any time directories being present.
Also renamed option zeroTime -> withZero for consistency with the noZero option
Disadvantage is that the BC values have to be specified in terms of hU
rather than U. The alternative would be to add complex code to map h
and U BCs into the equivalent for hU.

This is an experimental feature demonstrating the potential of MULES to
create bounded solution which are 2nd-order in time AND space.
Crank-Nicolson may be selected on U and/or alpha but will only be fully
2nd-order if used on both within the PIMPLE-loop to converge the
interaction between the flux and phase-fraction. Note also that
Crank-Nicolson may not be used with sub-cycling but all the features of
semi-implicit MULES are available in particular MULESCorr and
alphaApplyPrevCorr.
Examples of ddt specification:
ddtSchemes
{
default Euler;
}
ddtSchemes
{
default CrankNicolson 0.9;
}
ddtSchemes
{
default none;
ddt(alpha) CrankNicolson 0.9;
ddt(rho,U) CrankNicolson 0.9;
}
ddtSchemes
{
default none;
ddt(alpha) Euler;
ddt(rho,U) CrankNicolson 0.9;
}
ddtSchemes
{
default none;
ddt(alpha) CrankNicolson 0.9;
ddt(rho,U) Euler;
}
In these examples a small amount of off-centering in used to stabilize
the Crank-Nicolson scheme. Also the specification for alpha1 is via the
generic phase-fraction name to ensure in multiphase solvers (when
Crank-Nicolson support is added) the scheme is identical for all phase
fractions.
This development is back-ported from OpenFOAM-dev:

This version is very inefficient in parallel and does not provide the
-parallelSource or -parallelTarget options which will need to be
reinstanted in the future or we could revert mapFields to the
OpenFOAM-2.2 version.
