Global Energy Index
This is an estimate of the square root of the error in the total energy norm, which is the difference between the energy norm at the current pass and the exact energy norm, divided by the exact energy norm. To estimate the exact energy norm, the engine extrapolates the total energy norms of three successive passes.
This index handles the three successive passes as described for the Global RMS Stress Index.
Convergence index values always lie between 0% and 100%. The engine may calculate values greater than 100% internally, but it reports 100% in this case.
