[DFTB-Plus-User] error with dftb3

[Theodoros Leontiou]

Dear dftb+ experts 

I am trying to run DFTB3 with version 18.2. However, I get an error I
don't understand that has to do with the presence of 'DampXH = Yes' and
' DampXHExponent = 4.0' 

The error I get reads 

WARNING!
-> The following 2 node(s) have been ignored by the parser:
(1)
Path: dftb_in/Hamiltonian/DFTB/DampXH
Line: 48-48 (File: dftb_in.hsd)
(2)
Path: dftb_in/Hamiltonian/DFTB/DampXHExponent
Line: 49-49 (File: dftb_in.hsd) 

If DampXH and DampXHExpnonent are not used the program runs without
errors.  

Thanks in advance 

Regards 

Theodoros
