Hi everyone, I am trying to get field data(let's say e-field) from MPB with the command:
(run output-at-kpoint fix-efield-phase output-efield) But the outputs of e-field between twice calculation of the same code are very different, when check the output .h5 file of the e-field. It is obvious that the error is very big. Even though I have already reduced the tolerance of iteration to e-8, improved the resolution to 64 and set mesh size to 5. the difference between 2 calculations of the same code are still different, which seems different with big errors. I checked the output and the fixing e-field phase function does work, but the phase is different between two calculation. I need much more accurate e-field data I tried different geometries and the problem is similar. SO, I am wondering what elements influence the accuracy of the e-field and whether there are some effective ways to improve the accuracy of e-field output? Thank you so much. HRY
