How to make an animated Gif via gd1.pp -3dmanygifs

The Movie is created via these four Commands, with the proper Inputfiles:

 mkdir -p /tmp/UserName/garbage
    gd1 < DeMichele.gdf
    gd1.pp -ignore-profile < E-pp-in
    convert -loop 0 /tmp/UserName/garbage/AbsH*.gif DeMichele.gif

The Solver gd1 is used to compute the Fields. At selected Times the magnetic Fields on metallic Patches are stored.

     gd1 < DeMichele.gdf

The Postprocessor gd1.pp reads these stored Fields and writes GIF-Files.

     gd1.pp < pp-in

ImageMagicks convert converts these GIF-Files to an animated GIF.

     convert -loop 0 /tmp/UserName/garbage/AbsH*.gif DeMichele.gif

The Inputfile for the Solver gd1 is: DeMichele.gdf DeMichele-FullStruc-NomLoadOpt-27mm-ascii.stl DeMichele-added-vacuum-NominalOpt27mm-BASE4mm-ascii.stl DeMichele-loads-with-ext-NominalOpt27mm-BASE4mm-ascii.stl
