   * The number of RFs to be generated follows from
      * Nsim =10
   * The Random fields will be generated at the spatial points defined in terms of their coordinates. 
-     * The script tries to read a file in ```mechDir+'/GPData'```, where ```mechDir``` is the working directory, describing the list of spatial points. One example of points coordinates can be found in [rnnRF/GPData/coordinate_P_ZZ_OnPhysical_11.csv](./rnnRF/GPData/coordinate_P_ZZ_OnPhysical_11.csv) stored following 3 coordinates, point number and point volume (for a FE simulation).

One example of points coordinates can be found in [rnnRF/GPData/coordinate_P_ZZ_OnPhysical_11.csv](./rnnRF/GPData/coordinate_P_ZZ_OnPhysical_11.csv) stored following: finite element number (for a FE simulation); 3 coordinates; point number in finite element (for a FE simulation).
      * The random field number ```X``` is saved in the file ```mechDir+'/randomFields/RandField_X.csv'```, where ```mechDir``` is the working directory. The number of columns is the dimension of the random vector and the number of lines is the number of spatial points. One example of generated 2-dimension RF can be found in [rnnRF/randomFields/RandField_0.csv](./rnnRF/randomFields/RandField_0.csv). 
      * The random field number ```X``` along with the spatial points coordinates is saved in the file ```mechDir+'/randomFields/RandField_And_GP_X.csv'```, where ```mechDir``` is the working directory. The number of columns is the dimension of the random vector plus the 3 spatial coordinates and the number of lines is the number of spatial points. One example of generated 2-dimension RF can be found in [rnnRF/randomFields/RandField_And_GP_0.csv](./rnnRF/randomFields/RandField_And_GP_0.csv). 
   * The variable ```recomputePDF=True``` forces the evaluation of the spectral density matrix, which will be saved in ```mechDir+'/randomFields/H_pdf.dat'```.
