   * The RF is defined from the mean and standard deviation of the variables as well as from their correlation following for example for a 2-dimension RF:  
-     meanX = np.array([0.5,10])    # mean of variables
-     stdX = np.array([0.05,0.1])       # std of variables
-     rho = 0.2
-     R0_XY = np.array([[1, rho], [rho, 1]])

+     * R0_XY = np.array([[1, rho], [rho, 1]]) 
   * And from a the correlation lengths along the 3 direction
-     lc = [15., 15., 15.]            # correlation length

   * The Random fields will be generated at the spatial points defined in terms of their coordinates. 
-     One example of points coordinates can be found in [rnnRF/GPData/oordinate_P_ZZ_OnPhysical_11.csv](./rnnRF/GPData/oordinate_P_ZZ_OnPhysical_11.csv) stored following 3 coordinates, point number and point volume (for a FE simulation)
