+
+Description
+
+    Flame Surface Dennsity (FDS) combustion model.
+
+    The fuel source term is given by mgft*pc*omegaFuelBar.
+
+    where:
+          mgft: filtered flame area.
+          pc:   probability of the combustion progress.
+          omegaFuelBar: filtered consumption speed per unit of flame area.
+
+    pc is considered from the IFC solution.
+    omegaFuelBar is calculated solving a relaxation equation which tends to
+    omegaEq. This omegaEq is obtained from the flamelet solution for
+    different strain rates and fit using a expential distribution.
+
+    The spacial distribution of the consumption speed (omega) is obtained also
+    from a strained flamelet solution and it is assumed to have a guassian
+    distribution.
+
+    If the grid resolution is not enough to resolve the flame, the consumption
+    speed distribution is linearly thickened conserving the overall heat
+    release.
+
+    If the turbulent fluctuation of the mixture fraction at the sub-grid level
+    is large (>1E-04) then a beta pdf is used for filtering.
+
+    At the moment the flame area combustion model is only fit to work in a LES
+    frame work. In RAS the subgrid fluctiuation has to be solved by an extra
+    transport equation.
