MHD code simulated photospheric data:
IDL program to load the MHD data
IDL program to display two-dimensional images
See a note on GDL below.
NOTES:
1) The code works with conservative variables. To get the physical velocity the momenta have to be divided by the density.
2) The code uses normalized units for magnetic field. To get the magnetic field in cgs, it has to be multiplied by sqrt(4*pi)
3) In the code, x and z directions are horizontal. y direction is vertical.
4) The code uses cgs units. Velocity is in cm/s, density is in g/cm^3, temperature is in K, pressure is in dyn/cm^2.

If you have no IDL/Matlab/etc installed, you can try installing and using GDL: http://gnudatalanguage.sourceforge.net/
Note: GDL is slightly :) different from IDL (and much more buggy). I was able to compile and install GDL 0.9.3 using macports and the latest source from the GDL website.
If you use 0.9.3, to display two-dimensional images please download these
two source files instead of the one above and put them into the local
directory:
GDL program to display two-dimensional images
congrid.pro which is used by the above program
If you have GDL version less than 0.9.3, use the command tvscl (e.g. "tvscl, your_array_name(*,50,*)") to plot 2D picture.
