Added normalization of M magnitude at each iteration of 2nd order al…
…gorithm (#32) * added normalization in 2nd order evolveM and input file for debug * added normalizationto M * test commit #1 * test commit #2 * added field output lines * added python script for viz * turned off LLG-EM coupling * turned off LLG-EM coupling * fixed white space at line end * changed python script name * Delete M time sequence.ipynb duplicate file * clear up no coupling lines * clear up output functions * Delete M_time_sequence.ipynb * Added new line at end of inputs_3d.evolveM2nd * Added new line at the end of WarpX.cpp * make file easier to read Co-authored-by: Andy Nonaka <[email protected]>
