scuff-caspol broken? #146

Closed acmcclung closed 6 years ago

acmcclung commented 7 years ago

Wasn't able to get the scuff-caspol tutorial example to work:

scuff-caspol --PECPlate --atom Cesium --EPFile EPFile1

I've printed the EP and log files from running on my own machine, but the Simpetus AMI seems to produce the same error.

EPFile1: 0.000000 0.000000 2.000

scuff-caspol.log:

Fixed in c291e68. Thanks for the bug report.

Going forward I will probably merge scuff-caspol with scuff-ldos, since it doesn't really make sense to maintain two separate codes that do largely identical things. I would be curious to know what your use case is.

Feel free to ask more questions, or close the issue if satisfied.

Seems to be solved, thank you.

Our potential use case is pretty simple; we just want to know the CP potential for an atom next to a nanophotonic structure. I know there are other methods of calculating this sort of thing, but the simplicity of the setup in scuff-caspol is attractive. I will play with scuff-ldos; I assume eq. (A.1) can be adapted directly?
