Molecules in Abinit [SOLVED]

Hello all, I have a question linked with the calculation of molecules in Abinit. I used the tbase1_3.in input as test case but instead of H2, I'm doing NH4. The input file is as follow (The psp use the one of Psps_for_tests): ionmov 2 ntime 10 tolmxf 5.0d-4 toldff 5.0d-5 ntypat 2 znucl 7 1 natom 4 t...

Re: How to use foo_EIG2RD to calculate thermal corrections

Dear Jean Paul, If your version of Abinit is recent enough, you can use the python script to post-process your _EIGR2D and _FAN files. The scripts can be found in abinit/scripts/post_processing/temperature_para.py This script requires abinit/scripts/post_processing/rf_mods.py You can then run the sc...

Re: Problem with module etsf_io [SOLVED]

Oh I see. Thank you for the reply Yann.

There is no problem with having to do that.

I indeed though that I had to do something like that but could not find the information on doc/developers. Is that information written somewhere?

Kind Regards,

Samuel.

Modification of the paral_kgb behavior

Dear Developper, I recently realized that paral_kgb was automatically set to 1 if the number of cpu was not a multiple of the total number of k-points. Altought this is in principle a good idea, for the moment the paral_kgb default value is well 0 (deactivated). The problem is that the algorithm is ...

Dear Naresh,

You are probably trying to use a feature of BSE that is not coded yet in Abinit.

Could you send us (attached) your input file as well as the version of Abinit that you are using?

Re: Atom position in a Si slab, Calculation of a surface

The surface energy is simply the difference of energy between the bulk and the surface calculation. For exemple: If I get a total energy of -20 Ha for the primitive bulk cases (1 atom per unit cell for exemple) and a total energy of -58 Ha for three layers of Si and 7 layers of vacuum it means that ...

Re: Atom position in a Si slab, Calculation of a surface

Dear deepdrew, So the idea is that Abinit will replicate your primitive cell in the 3 directions. If you want to simulate a slab you can do for exemple: 3 layers of Si then 3 layers of vacuum then by replication it will again be three layer of Si etc.. To simulate a real slab you do not want the dif...
