Getting started in mesh scripts

Hello all,
I am trying to get started in creating meshes using scripts. Somehow i can not find any tutorials or example scripts. Can someone help me out with a link or some examples?

In particular I am interested in creating a brick-type mesh with double (coincident) nodes at some arbitrary points within the volume (they will be needed for the opening of a crack/ cavity at these locations in my simulation).

Thank you very much,
Daniel

You might review the information in the Help about scripting. For example, these topics will help in creating a journal file or Python script.

-Command Syntax
-Journal File Editor
-Python Interface
-APREPRO

Attached are two examples of a journal file and one Python file.
