GENERAL INFORMATION:
Under some conditions related to starting particles as function of time, the screen element erroneously displays the following warning:
>N Particle(s) started behind screen x. Particles are ignored

If this message appears, it is likely that particles that should be recorded in the output file are omitted. Please follow the installation instructions below to install an updated version of the screen element.

INSTALLATION INSTRUCTIONS:
Copy the enclosed .c files to the following folder:
c:\Program Files\General Particle Tracer\elems
(Please substitute the first part with your GPT installation folder when required).

Start GPTwin and specify:
  Elements/New
    Name: screen_fix
    Filename: screen_fix (without extension)
    DON'T create file
    Finish

  Elements/Compile GPT-Elems

Your new GPT executable should now be compiled with the new screen_fix element. TO use it, you need to replace screen by screen_fix in all your GPT inputfiles. If errors are encountered anywhere in the installation process, please notify us immediately.
