Sure, Tmolex offers an excellent choice. But there are only a few issues.
1. The program crashes if large number of molecules are present.

2. The choice of methods (basis set and other properties) are limited in Tmolex.

I used Tmolex extensively for few purposes, single-point calculation etc. However, I need to do calculations with aug-cc-pVQZ (Tmolex only has def2 basis).

Hi there,
I am trying to calculate ccsd(t)/aug-cc-pVQZ single point energy for a small molecule.
First I ran dscf (worked well) followed by ccsdf12 (still running).
Looking at ccsdf12 output file, I got this bizarre statement. A snap of the output is given below,

TURBOMOLE Forum General / Re: Running same method calculation on multiple molecules.
« Last post by uwe on June 13, 2022, 08:15:01 PM »
Hi,

sure, there are quite a number of options which all allow running calculations on lists of molecules. But before I start to list those, it seems that you would prefer to use TmoleX.

So let me first ask why you want to run TmoleX on a remote machine at all. While there are remote desktop solutions like RDP, VNC, Nomachine, Teamviewer or even the good old X11 server still works, it is highly recommended to install and use the graphical user interface locally on the machine you are using as a desktop. That guarantees a responsive user interface.

Is the machine you want to run the calculation on accessible by secure shell (ssh)? If yes, you can use the Run(network) button in TmoleX instead of the Run(Local) one when starting jobs. It asks you for the name of the remote machine, user name, password and the installation directory of the command line version of Turbomole on that machine. If you have all that, you can run jobs the same way you are used to on your local machine.
Queuing systems like PBS, SLURM, LSF, etc. are supported and jobs can be submitted to those from TmoleX too.

Would that be an option?

Hi,
I want to run PBE/def2-TZVP calculation on 1200 molecules. Now it can be done with Tmolex, but I have a problem with the graphic driver (probably) and it doesn't work as expected. Starting define module for each system is not a way. Is there any other way available so I can generate the input and run Turbomole in one go?

Dear all,


         I'm trying to plot the transition densities for a molecule having C1 symmetry with $soes 3 . By default the first excited state (of the first irrep)  is printed with the file name (vcao_td_a_001.1.plt).
   
 $curswitchdisengage
 $pointval transdens
 $tdlist
   irrep1 num1
   irrep1 num2
Those are the keywords I'm using to plot the transition densities (which is given in the manual) but still, the higher excited state is not printed having the same irrep a . How to sort out this ??
Thanks in advance

Dear Uwe:
Good to hear that this functionality will be implemented soon. It is very much needed.

Best wishes,

Hello,

you are right, cub files generated directly by the keyword

$pointval fmt=cub ...

do add the charge of the nuclei which in case of ECPs is not correct. Should be fixed in the next major release.

You could write standard plt format instead (just remove the fmt=cub option) and then use 'plt2cub' from here:

https://www.turbomole.org/turbomole/utilities/


to do the conversion. plt2cub should write the correct element identifiers also in case of ECPs.

Hi,
the official versions do not yet offer the possibility to manually set parameters for D4, I'm afraid.

The developer version does recognize
$disp4 --param <s6> <s8> <a1> <a2>
just as the stand-alone version of DFT-D4.

Thus, this functionality will be available in the next major release later this year (2022).
Regards, Uwe

Dear Turbomole experts:

I am trying to use a relatively new functional LH20t, for which the D4 correction was parametrized (10.1021/acs.jctc.0c00498). This functional is available in Turbomole 7.5.1, but it appears that the dispersion parameters are not available:

 Lh20t local hybrid functional

 DFA lh20t unknown
 ridft ended abnormally

The parameters of the D4 model (s8, a1, a2) for this functional are known and they are given in the original paper.

I wonder, is there a way I can manually supply the values for the D4 parameters? (of course without recompiling Turbomole).

Thank you in advance.

Dear Developers,

I have come across a minor problem with the plt tool. For calculations using ECP basis sets the plt tool presents any atoms as Z - Nelectrons in the ECP. For example, my molecule has 94Pu and I am using the Dolg 60 electron ECP so the cub file created by the plt tool presents the 94Pu as 34Se. I double-checked and 93Np becomes 33As in the cub file confirming my suspicions about the interaction of plt with the ECP.

I compared the wavefunctions generated by both plt and tm2molden and they appear to be the same. The ECP atoms can be fixed manually by editing the cub file e.g. changing 34 to 94 but maybe you could implement a fix for this?

I should also note that I am using Turbomole 7.3, this may be fixed in newer versions?
