SWMF - Downloads


The SWMF code can be downloaded free of charge, but there are some very real system requirements and limitations that prospective users need to be aware of. While SWMF is not export-controlled, we are required to track users of the code through a Registration Form before distribution of the code can be permitted.

To get you up and running models quickest, just follow the 3 step process, and you'll be ready to Download files.


Step 1: Review System Requirements


SWMF is a highly tuned software framework and has some very specific requirements that must be met to use it:

  • UNIX, Linux, or MacOSX operating systems
  • FORTRAN 90 (F90) compiler
  • An MPI (Message Passing Interface) library
  • A Perl interpreter

On low resolution grids SWMF can run even on a single-processor work station. However, to do physically meaningful runs with several components, the SWMF should be run on a parallel machine.

If you don't have an FORTRAN 90 compiler, we suggest the GNU FORTRAN Compiler (version 4.5 or later) (http://gcc.gnu.org/fortran/), or the Intel ifort compiler (http://software.intel.com/en-us/intel-compilers).

If you don't have an MPI library, we suggest OpenMPI (http://openmpi.org).

Step 2: Limitations & License


Review the Limitations


  • The current public release of the framework is a prototype for modeling the Sun-Earth system and for doing space weather studies. This prototype should be considered preliminary and should only be used in close collaboration with CSEM.
  • Modification of the BATSRUS component of the SWMF can be done through the use of "user files" which allow modification of core pieces of the model such as boundary conditions and source terms.
