  I have not found any information in the so called 'reference manual' as to what units Lumerical results are displayed in.
  For example, in the Frequency domain power monitor output displayed in the screenshot below, what units are the results(the coloured contours...)?
  
  Thanks for your help!

  In general, FDTD results are in SI units. Please refer to this article: https://optics.ansys.com/hc/en-us/articles/360034397034-Units-and-normalization-conventions-in-Lumerical-solvers
  E field has v/m unit.

  Thanks for your reply. I am aware that E fields have units of v/m, but how do I know what is being displayed in the charts? Is it E field? Is it something else? The so called 'reference' manual does not give any indication as to what parameter is represented by the contour colours in a 'Frequency domain power monitor'. Is it E field? Is it power? Is it...? Thanks
