Howto visualize (e.g. on atsccs28)


- change into geometry directory
- start up avs
- select "application" on the startup menu
- use "file / load application" to load the program avs.v contained in the 
  directory geometry
- within the main menu: 
    - double click on entity "Read Field"
    - replace the filename by the absolute filename (avs does not support 
      relative paths, that's a pitty)
- change into the visualisation window
    - select modules "Read Field"
    - use "Step Forward" and "Step Backward" to go through the animation
    - use "Continous" checkbox to start the animation
- have a lot of fun
