Arndt,
First of all, Thank you very much for your reply.

I'm sorry this is not average, it is RMS value.
In deal.ii, from step7, L2 norm is calculated like this...
L2_norm= sqrt (sum_i [error_i^2])
But What I want is
L2_norm = sqrt(sum_i [error_i^2]) / sqrt(the number of cells)
So, I thought most values in the plot Error_fe1.png sholud be order of
L2_norm (that is sqrt(sum_i [error_i^2]) / sqrt(the number of cells))
Because summation of error^2 is divided by the number of cells
But the result is not...
most values in Error_fe1.png are 10^3 times higher than L2_norm (in this
case 4.7163e-07)
Is it wrong....?
Thank you.
Kyusik.
