F77 file readers

From OpenGGCM

!!!These are a bit old but still work just fine:

These filenames have the suffix '.txt' because mediawiki does not like '.f' attachments. Just rename the txt to f.

• F77 code to read 3d fields: Media:mhdread.txt. Documentation is in the file.

• F77 code to read ionosphere files Media:ioread.txt. Documentation is in the file.

• F77 code that computes open/closed boundaries and a few other things. This code uses the face centered B and edge-centered E. This should be a decent starting point for particle tracing with Lorentz force. Media:iocl4.txt

• F77 code: field line tracer, used in RCM coupling. THis code uses face-centered B and also uses a smooth blend of MHD fields with dipole. Media:filedlinetracer.txt
