Dear Dr. Huu Chuong Nguyen,


I see from your input that you are trying to run a spin-polarised, DFT+U plus empirical dispersion plus smearing calculation coupled with the Environ plugin. Although I would assume that these different features are all compatible with Environ, I have never tried such a combination and it may be that there are some bugs in the combination that lead to the segmentation fault. Have you tried running a simplified calculation to isolate the source of error (say removing the Hubbard U, the dispersion, doing a spin-unpolarized calculation)? Moreover, you may want to simplify the Environ input as well, trying to only test one embedding effect at a time: for example you can activate only the dielectric screening by setting environ_type = 'input' and env_static_permittivity = 78.3 (assuming water is what you are looking for). Or you can try to only activate the surface tension contribution by setting env_surface_tension to an arbitrary value. This would also help in understanding where the source of the segmentation fault is. Unfortunately this seems like an expensive example to debug from scratch, if you can provide more details or a simpler case where the problem occur, I would be happy to have a look and see if we can fix the problem. Moreover, if you can send me the output of your tests I could try to see if there is any indication of a problem already from those files.

Thanks for reporting the issue!

Best regards,

Subject: [Pw_forum] Crash with Environ-0.2

Hello,


I am running a relax calculation with QE 6.1 and Environ-0.2. In vacuum, the calculation finish without problem but when I change the medium to water. The calculation always suddenly stop after "     add environment contribution to local potential" with an ominous segmentation fault. This bug is reproducible on all machines that we have but I cannot figure out from where it could come from. Does anyone has had a similar issue or has an idea on how to solve it?
