Second Derivative
 

I have some doubt about second derivatives for post-processing in F6.3.

As per the user manual (p.30-21), adaption curvature of desired variable gives its second derivative. A lot of posts in this forum have talked about obtaining the second derivatives through various methods but as far as I can check, none of them have mentioned this.

Will it be proper to use the adaption curvature information for second derivative data?

Any response is highly appreciated.
