Estimated error in the energy norm OR the error norm.

Hello everyone,

I am having trouble with something that I can't seem to find any help about in COMSOL support. I only see it mentioned very little and not in very much detail in the help documents. I am wondering how to calculate the estimated error in the energy norm (I've seen references to the "error norm" on this site, is that the same thing?). By energy norm, I am referring to the definition found in these two texts (if you are not familiar with the term, if you are, sorry for insulting your knowledge of the FEM :) www.math.cornell.edu/~demlow/425/chap5.pdf or www.cs.rpi.edu/~flaherje/pdf/fea7.pdf.

Thank you for your help in advance,

John

Re: Estimated error in the energy norm OR the error norm.

I am still wondering if there is anyone who knows how to answer this question? I'm sorry if it's a little too theoretical...
