[CP2K-user] [CP2K:16398] change of Ensemble in MD run

[Thomas Kühne]

You can use EXT_RESTART and directly change the ensemble in the input, but in that case you have to be careful what is it exactly what you restart. 
Alternatively, you can do it the way you mentioned, but please also adapt the cell! The most simplest way is to take the *.restart file change the ensemble 
and rerun. 

Best, 
Thomas Kühne
