I'm running a Numforce calculation and it has finished without any issues. I can see all the modes and their corresponding frequencies, however my output files says just this:
rdgrad ended normally
force ended normally
Data group $vibrational normal modes not found in file vib_normal_modes
Data group $vibrational spectrum not found in file vibspectrum
I need to be able to visualize the normal modes. Do you know why the vib_normal_modes and vibspectrum files are empty? Many thanks in advance
