-In particular, the second preliminary step indicated in the above publication is now automatically perfomed. This speeds up the preparation of the preliminary steps and reduces accidental errors.
+In particular, the second preliminary step indicated in the above publication is now automatically performed. This improvement speeds up the preparation of the preliminary steps and reduces accidental errors.
 The only step that must be performed manually is the extraction of both project and design variables from HFSS.

+The only files that are needed to launch the simulations are:
+Base.aedt
+BaseNoSignposts.txt
+VariablesDesign.txt
+VariablesProject.txt
