Future Advancements in FEA 4

[Scobie33]

Hi there,

I've been reading quite a few papers on the Nurbs-Enhanced Finite Element Method (NEFEM) and I was just wondering what you guys would consider as its greatest advantages/disadvantages?
From what I can see, it appears to be far more accurate in the vast majority of cases. Also, why are no FEA packages (such as Ansys) using this?

Finally, what do you consider to be some of the upcoming advancements in FEA technology in the next 10/20years in terms of accuracy of solution and computing time?

Cheers, any insight appreciated

I've had a look at around five doctoral thesis papers (i'll supply links as soon as i get a chance) that all point to the idea that NEFEM is far more accurate than convential methods (Isoparametric FEM etc).
It also appears to be far less computationally demanding due to using more coarse meshes but the papers go into so much detail with a lot of it going over my head so perhaps you lot might understand them better

I understand where you can coming from, Scobie33. A lot of the content in this area is highly mathematical in nature - which is good and bad, from my perspective as a practitioner. It is good because it makes me "feel/hope" smart people have spent time in ensuring the underlying physical principles aren't violated and mathematical machinery is reliable. It is bad because reading advanced mathematics requires a lot of patience, perseverance, and time - which is, typically, in short supply when you are in the industry.

So, unless the content is closely related to what I am doing, I have, for the most part, given up on reading mathematical papers. Instead, when I have time, I try to find video lectures by some of the well-known folks and focus on following the crux of the matter. Fortunately, these days, there are plenty of such lectures out there to keep me engaged.

This is, strictly speaking, not directly related, but is nevertheless an interesting reading about future of analysis and designs:

Interesting link, bkal. Thanks for sharing.
