[CP2K-user] [CP2K:13190] How can I ramp a temperature up from a starting low temperature or ramp downward from a high temperature?

[Thomas Kühne]

Nope, 

values smaller are for annelaing/quenching, whereas values 
larger than 1 can be used to exponentially increase the 
temperature. The value is used to rescale the temperature, 
which is then used as the target temperature for your 
thermostat. 

Cheers, 
Thomas

After some time at 1000K, when the block begins to exhibit equilibrium conditions, I'd like to take it back to a solid room temperature state at 298K. What is the best method to accomplish this? I'm using a CSVR thermostat currently at 1000K. But I'm not sure how to accomplish the annealing (298K to 1000K), quenching (1000K to 298K), and tempering (400K) steps or how to use the annealing function to accomplish all of these three.
