How to generate asc file for Ansys nCode DesignLife standalone with mech-dpf?

Javier Vique

If integrated systems of Ansys nCode DesignLife are used, a file called dlnamedselections.asc file is created automatically. However, that's not the case if Ansys nCode DesignLife standalone is used. How to do it with mech-dpf?

Here a script that can be included in a Python Code object in Solution that creates the *.asc file to be used in Ansys nCode DesignLife with all named selections except for those who start with under hyphen character (which are usually internal named selections).
