<![CDATA[Xtracting S11 data via python]]>Hi everybody,

I am trying to extract S11 data of an EdgeSource sensor from a broadband simulation via python, however I found only the way how to extract frequency data.
How can I access the S11 data as well? Part of my code is

simEM_results = sim.Results()
S11_axis = simEM_results["EdgeSource (Dipole)"]["Reflection Coefficient(f)"].Data.Axis

S11_data = ???

Basically I am looking for equivalent to SEMCAD X 14.8.6 XNumPy.AsArray() function.

Thanks,

Spuky

This makes the scripts easier to maintain in the long run:

S11 = simEM_results["EdgeSource (Dipole)"]["Reflection Coefficient(f)"]
assert S11.Update(), 'Failed to update pipeline'
S11_data = S11.Data.GetComponent(0)

S11 = simEM_results["EdgeSource (Dipole)"]["Reflection Coefficient(f)"]
S11.Update()

Thank you for your quick answer however when I do

S11 = simEM_results["EdgeSource (Dipole)"]["Reflection Coefficient(f)"].Update()

The S11 is True (Boolean) and it does not contain any Data.

Regards,

  1. load the data object (i.e. read data from disk and push it through the postprocessing pipeline)
S11 = simEM_results["EdgeSource (Dipole)"]["Reflection Coefficient(f)"].Update()
  1. get the data you need from the data object
S11_axis = S11.Data.Axis
S11_data = S11.Data.GetComponent(0)

Note that, once you have executed step 1, you can easily explore what the data object contains by using auto-completion in the Console environement: just type "S11" followed by a dot (.) in the Console and you can navigate its data structure.
