[CP2K-user] [CP2K:21997] Tabulated external force potential

[Ioachim Dusa]

Dear CP2K community, 

I was wondering whether it is possible to specify an external potential for 
the force and energy evaluation dependent on the atomic positions using a 
tabulated file. FORCE_EVAL/EXTERNAL_POTENTIAL does not seem to have this 
option; only FUNCTION for which the analytical form is needed, which in my 
case is too complex to implement in the input file. Are there any 
workarounds? 

Thank you very much for your help!
