+Decay of homogenious incompressible isotropic turbulence
+
+This case is based on the set-up of Comte-Bellot and S. Corrsin [1]
+
+The mesh comprises a block-structured cube divided into 64x64x64 cells, with
+a box length of 9*pi cm.
+
+Turbulence is initialised using the target energy spectrum supplied in [1] (see
+table 3).
+
+For more information, see:
+
+ https://www.openfoam.com/documentation/cpp-guide/html/verification-validation-turbulent-decay-homogeneous-isotropic-turbulence.html

+ isotropy of grid-generated turbulence," J. Fluid Mech. 25, 657 (1966).
