+Mesh converters

+Most mesh formats use cyclics in a single patch (i.e. the old way).
+The converters have been adapted to use the patch 'oldCyclic' instead of
+'cyclic'. oldCyclic uses the 17x automatic ordering but writes 'type cyclic'

+Description
+    Solver for 2 incompressible, isothermal immiscible fluids using a VOF
+    (volume of fluid) phase-fraction based interface capturing approach.
+
+    The momentum and other fluid properties are of the "mixture" and a single
+    momentum equation is solved.
+
+    Turbulence modelling is generic, i.e.  laminar, RAS or LES may be selected.
+
+    For a two-fluid approach see twoPhaseEulerFoam.

+Description
+    MULES: Multidimensional universal limiter with explicit solution.
+
+    Solve a convective-only transport equation using an explicit universal
+    multi-dimensional limiter.
+
+    Parameters are the variable to solve, the normal convective flux and the
+    actual explicit flux of the variable which is also used to return limited
+    flux used in the bounded-solution.

-    Foam::fvc::smooth
+InNamespace
+    Foam::fvc
 
 Description
-    Function that uses smoothData to apply spatial smoothing of a
-    volume field using the FaceCellWave algorithm
+    Provides functions smooth spread and sweep which use the FaceCellWave
+    algorithm to smooth and redistribute the first field argument.
+
+    smooth: smooths the field by ensuring the values in neighbouring
+            cells are at least coeff* the cell value.
+
+    spread: redistributes the field by spreading the maximum value within
+            the region defined by the value and gradient of alpha.
+
+    sweep: redistributes the field by sweeping the maximum value where the
+           gradient of alpha is large away from that starting point of the
+           sweep.

+Class
+    Foam::fv::localEulerDdtScheme
+
+Description
+    Local time-step first-order Euler implicit/explicit ddt.
+    The reciprocal of the local time-step field is looked-up from the
+    database with the name provided.
+
+    This scheme should only be used for steady-state computations
+    using transient codes where local time-stepping is preferably to
+    under-relaxation for transport consistency reasons.
+
+    See also CoEulerDdtScheme.

+
+Description
+    Local time-step first-order Euler implicit/explicit ddt.
+    The reciprocal of the local time-step field is looked-up from the
+    database with the name provided.
+
+    This scheme should only be used for steady-state computations
+    using transient codes where local time-stepping is preferably to
+    under-relaxation for transport consistency reasons.
+
+    See also CoEulerDdtScheme.

 *** *New* compact binary I/O for faces and cells. This speeds up reading/writing meshes in binary.
 *** *Updated* runTimeModifiable
