+This is an example to run a cyclone base case (see Dimits et al. 2000) with the GYACOMO code.
+
+you can run it sequentially in single precision typing : ./gyacomo23_sp 0
+or in parallel (here double precision) : mpirun -np 6 ./gyacomo23_sp 1 6 1 0
+
+The code has to be compiled before and the executable should be located in the /gyacomo/bin/ folder.
