The Templates model objects can be generated and configured using the GenericToolkit module of the Python API:

import GenericToolkit

print GenericToolkit.ListToolkits()

seft = GenericToolkit.Create('SEFT')

print seft.Parameters.DumpTree()

seft.Parameters.Geometry.Environment.Frequency.Value = 1e5
seft.Parameters.Geometry.Geometrical.CurvatureRadius.Value = 85
