+To show how the parameter and material files can be generated, we add here the C program that was used for the calculations: {{ :app:sersgen2.c | sersgen2.c}}. It allows creating wide range of geometries like shown in the above images. The main types of nanorod placements are (A) linear, (B) triangular, (C) rectangular, (D) pentagonal, (E) circular and (E-F) various amounts of hexagonally packed rods as shown in the following image.
+{{:app:allmodels.png?600|}}
+User can control the size of rod components, periodiciy and add some imperfections, like imperfection in the rod position and relaxation of the rod, as shown here.
+{{:app:modifications.png?600|}}
+This can be further combined with ability of GSvit of creating surface roughness. In this way dependences of the local field enhancement on some particular parameters can be generated, combining the simple C program, GSvit and some post-processing, e.g. in Gwyddion or using batch processing tools derived from Gwyddion.
+As an example, the above basic model types provide the following field distributions in the spheres plane (for polarization along the x axis).
