Dear Yannick,
thank you very much for your help, specifically for this use case but also for pointing out TURBOTEST to me.
Best regards

Rirpa / Re: how to use sigma functionals in TM 7.8

Dear Franz,

based on the control in the test directory /TURBOTEST/rirpa/short/O2.GRAD.SIGMA you need to add the functional in the rirpa data group.

$rirpa
    sigmafunc pbe_s1
    npoints 100
    gausslegendre
    rpagrad

Hope this helps,

Yannick

Rirpa / how to use sigma functionals in TM 7.8
« Last post by fsymalla on January 11, 2024, 05:05:24 PM »
Dear Turbomole experts,

 in the TM 7.8 release notes it is written about the implementation of :
"rirpa: energy and analytical gradient for various sigma functionals"

I would like to try these sigma functionals, however i can not find any documentation or options in define.
Could someone give me an example of how to use these?

Best regards
Franz

Dear Franz,

TMHF and TMHF-3P use the original B95 correlation (I am one of the authors of the TMHF functional familly). Other local hybrids by the Berlin group use a modified version (lh20t etc.). I guess that 7.8.1 will be available in summer 2024. You could ask the official support for a preversion.

Best,

Yannick

Dear Yannick,
thank you very much indeed! do you know what date is aimed for, for that release?  Regarding modified versions of B95 in local hybrids: do you know whether it was modified in the case of tmhf?

Best

PS: I have implemented it accordingly for V7.8.1. The exchange and correlation energy of local hybrid functionals is now stored as done for the other functionals in both one-component and two-component runs.

Dear Franz,

Currently, the individual energy contributions are only printed in the developers' version, directly in the dscf or ridft output. We used that for the development of theTMHF  functional but disabled some output in the official release (I do not know the reason for that anymore). I could add that information for the next version, likely 7.8.1.

Your approach only works for the original B95 correlation. Many local hybrids use a modified version of B95.

Best,

Yannick

Dear Turbomole experts,

I would like to know the correlation energy in calculations using TMHF and Lh12ct-SsifPW9  functionals.
in the $subenergy section of the control file both exchange and correlation contirbutions are listed as zero for both functionals. Is there a way to access the correlation energy some other way?
If it can not be printed, would it give the correct results if i define a functional using xclib which in case of TMHF would only consist of the B95 correlation functional which according to https://doi.org/10.1063/5.0100439 is the one used for the correlation energy in tmhf, and rerun using $scfiterlimit 1 and $scfdamp start=100000000000 and read of the total energy from that run (or for that matter even use any functional which uses B95 for correlation and use the correlation energy printed in $subenergy)?

Thanks for any help,
best regards,
Franz

update:
i tried my own suggestion with functional libxc 240 (MGGA_C_BC95 (id=240): Becke correlation 95)
also no correlation energy is written in $subenergy but i can read of the exchange correlation energy in the normal SCF output
Exc = -1.40427110940     Coul =  312.223154474
 and since i have no exchange functional this should be the correlation contribution only.
now i get some number in a clumsy way. if someone could comment on whether this is the correct one for the tmhf case it would be appreciated, or of course if there is a better way to just write out the energy, because for  Lh12ct-SsifPW9 i did not find the appropriate correlation functional in libxc.

Hello,

I was looking for a "feature request" branch in the forum but could not find such and therefore will put it here.
It would be really helpful and convenient if NTOs could be generated in the .molden format files containing both molecular geometry and the densities, instead of .plt
Then for analysis and visualization one could use any visualization program that works with .molden files.

Thanks

Treatment of Solvation Effects with COSMO / Re: cc2cosmo/ricc2 fails with CC2
« Last post by shafikoff on December 25, 2023, 09:37:58 PM »
Hello,

Do I understand it right that COSMO is still not implemented to run at CC2 level in version 7.7?
