Dear all,
I need to calculate NMR shielding tensors on dummy atoms (no nucleus and no basis functions, serve only as passive observers). Is there a way to do this in ATK?
- I found that the plane wave calculator can be used to calculate the shielding tensors but it does not seem to support the ghost atoms.
- Is there any way around such as defining my own atoms with no charge and no basis functions?

Thanks for help
Vaclav

Installation and License Questions / Error on Windows 10

Hello,
I installed the 2020 QuantumATK version on Windows10. After launching the program, I got a window with the error shown in the attached text file. The 2019 verison worked fine. I would appreciate any help to solve this problem. Thanks a lot, Vaclav

Hello,
I wrote a script which shifts a molecule on a graphene sheet surface and calculates Total energy. Everything seemed to work fine when just a few thousands of points are calculated but with a large number of calculated points I got this error message:

TremoloXCalculator: Cart_create with procs 1 1 1 and periods 1 1 1 failed
Traceback (most recent call last):

I am new to programming so I admit there might be an error in my script but I could not figure out what could be the source of this error message. Could anyone please explain this error message and direct me how to avoid it? I attached the full script.

Thanks a lot for any advice.
