Re: [Wien] Query regarding clean_lapw
Sorry, it should be TEMP instead of TETRA in the study after lithiation while keeping TETRA in the study before lithiation (with HSE06 for both the cases with alpha=0.25) On Sun, 12 Jun 2022 at 13:44, shamik chakrabarti wrote: > Dear Prof. Tran, > >I have obtained convergence by introducing the > following parameters; alpha=0.25, mixing scheme = PRATT, mixing > parameter=0.05, TETRA instead of TEMP in case.in2. > Now, I want to compare the energy before lithiation & after lithiation.

Re: [Wien] Query regarding clean_lapw
Dear Prof. Tran, I have obtained convergence by introducing the following parameters; alpha=0.25, mixing scheme = PRATT, mixing parameter=0.05, TETRA instead of TEMP in case.in2. Now, I want to compare the energy before lithiation & after lithiation. I have obtained the energy before lithiation using the parameter, alpha =0.25, mixing scheme = Msr1, mixing parameter=0.2, TEMP in case.in2 Do you think that these two scenarios are comparable? or I may need to invoke the same parameters in the system before lithiation? with regards, On Sat, 11 Jun 2022 at 13:35, shamik chakrabarti wrote: > Dear Prof. Tran, > > Yes the system is a metal.

Dear Prof. Tran, Yes the system is a metal.

Re: [Wien] Query regarding clean_lapw
If the calculation really did not seem to converge (:ENE was oscillating or :DIS was staying at some high value for ever) then yes it may be better to delete the case.vector files with clean_lapw and regenerate case.clmsum in some way (with dstart or with some functional, PBE or PBE+U). I can not remember the details of your system and convergence problems (was it a metal?), but this has already happened that I could converge only by using PRATT with a very small mixing factor (0.05) in case.inm. Using TEMP instead of TETRA in case.in2 may be worth to try.
