Hello everyone,</div>

I have a problem regarding calculation of stress tensor and pressure for a monolayer in the presence of electric field (resp. dipole correction).</div>
<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
I am trying to do vc-relax calculation (cell_dofree='2Dxy') of NbSi2N4-TaSi2N4 heterostructure (regarding those monolayers independently, they have very close lattice constant).</div>
<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
The problem is that if I merge them into heterostructure, I observe big negative pressure in z direction with very forces and energy already satisfying their tresholds.</div>
<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
My first guess for such behaviour was related to the dipole moment between periodic images of the system in z direction, so I tried to add dipole correction to test this hypothesis.</div>

<u>However, despite I specify 'tstress=.true.', I can't see any information about pressure or stress in output file.</u> In data-file-schema.xml there is one block related to stress, which seems to be stress calculated in the last step (scf) of vc-relax calculation,
but nothing more. For vc relax without electric field I can see there stress tesnor after each relax step.</div>

Is this expected behaviour of the code or do I miss something?</div>
