+Class
+    Foam::fixedPressureCompressibleDensityFvPatchScalarField
+
+Description
+    Calculate compressible density as a function of pressure and fluid
+    properties.
+
+    Example of the boundary condition specification:
+    @verbatim
+        inlet
+        {
+            type        fixedPressureCompressibleDensity;
+            p           p;               // Name of static pressure field
+            value       uniform 1;       // Initial value
+        }
