Hello Matej,

there are several possibilities to make such geometry in Yade. All of 
them works with facets (triangular elements), that represents the 
geometry. So you can:

a) use some method from yade.ymport module [1]. Various formats are 
supported - gmsh, gts, stl, unv. This will load facets (triangles) from 
a file (which was somehow prepared in advance). See for example unv 
example [1], the mesh was created using free mesh generator Salome [6].

b) create the geometry directly in python script using gts module [3] 
(this documentation should be improved), see for example [4] or [5].

If you have already the geometry in a CAD model that can save it to 
readable form, we can implement methods to import another format

good luck in your work and if you had any questions, just ask

Jan
