+Class
+    Foam::fv::solidificationMeltingSource
+
+Description
+    This source is designed to model the effect of solidification and melting
+    processes, e.g. windhield defrosting.  The phase change occurs at the
+    melting temperature, \c Tmelt.
+
+    The presence of the solid phase in the flow field is incorporated into the
+    model as a momentum porosity contribution; the energy associated with the
+    phase change is added as an enthalpy contribution.
+
+    Based on the references:
+
+      1. V.R. Voller and C. Prakash, A fixed grid numerical modelling
+         methodology for convection-diffusion mushy phase-change problems,
+         Int. J. Heat Mass Transfer 30(8):17091719, 1987.
+      2. C.R. Swaminathan. and V.R. Voller, A general enthalpy model for
+         modeling solidification processes, Metallurgical Transactions
+         23B:651664, 1992.
+
+    The model generates a field \c \<name\>:alpha1 which can be visualised to
+    to show the melt distribution as a fraction [0-1]
