The LFM is a global MHD model written by John *L{*}yon, Joel *F{*}edder and Clark *M{*}obarry.  It is primarily used to better understand Earth's Magnetosphere.  The LFM can be coupled with a variety of models to aide in understanding of the physical processes in Geospace , such as:
* Magnetosphere Ionosphere Coupler/Solver ([LTR:MIX])
* Thermosphere Ionosphere Electrodynamic General Circulation Model ([TIEGCM|])
* Rice Convection Model ([LTR:RCM])
The coupled combination of models is called the LTR (LFM-TIEGCM-RCM).

This wiki serves as the canonical reference the software that comprises the LTR.  This documentation contains limited scientific descriptions of the models; this wiki is intended as a guide to compiling & executing the code.

{info:title=Note}The LTR models and documentation are constantly evolving. This wiki documents the latest release. In some cases, this includes documentation for unreleased/upcoming features. You should sign up to [the LTR-announce mailing list|] and make sure you're using the [latest release|]. You can find a list of upcoming features via [the LTR roadmap|].{info}
