How to set the Number of freqs in real time NLO calculation

Post by AmberLee123 » Mon Jan 31, 2022 3:31 am

When repeating the calculation in tutorial (http://www.yambo-code.org/wiki/index.ph ... r_response),

there is a line like

# [NL] Number of freqs :5

in o-file (like o-QP_ypp.YPP-X_probe_order_2)

I tried to search the variables in http://www.yambo-code.org/wiki/index.ph ... es#KfnQP_E ,
but still don't know how to set he number.

More data points are needed to make a nicer NLO chi(2) curve. So how to increase the number of frequencies?

Thank you!

I found it, it's NLEnSteps .
Thank you.

Well, I set it and run the program yambo_nl again, but ypp_nl gives the same result...

Dear AmberLee123

I did understand your reply, did you solve problem or not?
or do you have another problem with ypp_nl now?

best

Unfortunately, I have not solved the problem yet. When changing NLEnSteps, running yambo_nl, running ypp_nl; the results are the same.

Problem solved. Just as claudio said before( viewtopic.php?f=9&t=1802&sid=4fd95b1897 ... 4d64c8cc39),

"
run them without the -J and -C options, directly in the SAVE folder
"

Then everything works well.
