[CP2K:6374] FES for metadynamics in polar coordinates

[Raphael Peltzer]

Thanks for the quick answer. I don't know how I could not think of 
post-processing the fes.dat. 

Yes, it does not change the shape, but makes it easier for me to visualise 
alternative routes between the two wells and a third one that I actually 
observed in a trajectory. I will have to redefine the CV's anyways for a 
second run, I think.

Cheers for the great answer, I marked the topic as finished
