Re: [Wien] Query regarding clean_lapw

Not only the last 72th iteration, but all 72 iterations. I want to see 
how :ENE and :DIS behave.

You can try to restart with TETRA the calculation that you

with TEMP (clean_lapw should not be executed after the TEMP
calculation in order to have the case.vector for restarting with
TETRA). Maybe the TETRA calculation will this time converge.

Otherwise, you would need to run the other calculations also

TEMP.

Be careful and check if your calculations with   PRATT 0.05   are really 
converged and check :ENE AND :DIS


With small PRATT mixing some pseudo-convergence can happen and in 
general I'd recommend PRATT mixing only for nasty cases and a couple of 
steps, before switching back to MSR1.

Re: [Wien] Query regarding clean_lapw

2022-06-13 Thread fabien . tran
In general, the total energies that are compared need to be obtained 
with the same setting. So, all the total energies have to be obtained 
with either TETRA or TEMP.


You can try to restart with TETRA the calculation that you converged 
with TEMP (clean_lapw should not be executed after the TEMP calculation 
in order to have the case.vector for restarting with TETRA). Maybe the 
TETRA calculation will this time converge.


Otherwise, you would need to run the other calculations also with TEMP.

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?

I can not remember the details of your system and convergence

only by using PRATT with a very small mixing factor (0.05) in

Using TEMP instead of TETRA in case.in2 may be worth to try.

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)

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?
