If you like using Emacs, be sure to download the ansys-mode file for syntax highlighting.  (It works with versions 22 or 23 of Emacs, although the APDL commands it supports are up to ANSYS 11.0, not 12.0.1, at the time of this writing, so new commands in 12.0 won’t be colored.)

One for LS-DYNA keyword files can be found here, although it requires registration to download.
