1. Compile the code
cd test
make m3d
2. Run examples
cd prism
../m3d cube.node cube.ele site.dat
cd pipeline
../m3d pipeline.node pipeline.ele site.dat
3. Plot results using matlab (higer version of matlab is needed)
cd prism
run plot_profile.m
cd pipeline
run plot_contour.m

5. format for input files
5.1 node file and site file
the number of 3D points
each line is id, x, y, z
5.2 element file
the number of elements
each line is element id, id of 4 nodes(id is defined in node file), magnetization vector M(Mx,My,Mz)
6. format for output file. Please see the main body of the article (section Implementation)
