[FLASH-USERS] Query - flash user guide (divergence error calculation)

[Priyesh Kumar]

Dear Sir, 
There is a contour plot of the divergence of the magnetic fields i n the Magnetohydrodynamics Rotor test problem section of the FLASH User's Guide (pages 502-505), which shows the effectiveness of the divergence cleaning scheme used in the simulation code. I have a query related to the calculation of the divergence error of the magnetic fields, Whether that is any normalized quantity to quantify the impact of the divergence error or directly calculated from the difference of magnetic field in each directions ( using the formula, del.B = (del_Bx / del_x) + ( del_By/del_y). 


Thanks!
