[Pw_forum] some input parameter

[chenjie gu]

Hi Pwscf User, when reading the input parameter,I am not very clear, here as
follows, can you give me some explaination:
nraise: how do we define a nraise step?

for ion_temperature=andersen: the collision frequency parameter is given as
nu=1/tau defined above, so nu*dt=1/nraise:here what is nu, tau?

thank you so much,
