 Given an initial field, we can also decompose it into the combination of eigenfunctions and then find out a cancelling field to obtain a force free state.[[BR]]

+= Resistive Field in Magnetized Cloud =
+
+The field relaxation due to resistivity is studied with the magnetized cloud problem listed above. The resistivity solver is tested using the interface test and the Harris sheet problem to be working in parallel AMR.[[BR]]
+The magnetic pressure in interface problem test:[[BR]][[BR]]
+[[Image(http://www.pas.rochester.edu/~shuleli/maginter.png, 20%)]][[BR]][[BR]]
+This test is done for x, y, z oriented fields separately. The interface expansion matches the theoretical calculation. [[BR]]
+The Harris sheet test problem requires a resolution of about 500*1000 to resolve the Sweet-Parker region effectively. This resolution combined with the requirement of many crossing time to develop the horizontal flow, make the problem not really suitable for 8 processor test. The following image shows the time evolution of field lines in time 0.1, with reduced resolution. The run time required is around 55.[[BR]][[BR]]
