Also thanks for writing a very insightful blog. I enjoy reading your blog. You have some good intuitions. I actually come from the fluid dynamics background, but now I was tasked to do some FEA, as well. A very challenge road for me, and I find your blog very useful. Thanks, and please - keep up the great work!
The way I perceive the 'problem' of differences: 1. CFD is a branch of research concerned with numerically solving problems in fluid dynamics 4. My current "field of interest" is mostly related to composite-like structures think of car radiators with tubes and corrugated foils as fins.
I would be very interested to see your take on the derivation of orthotropic properties of such structures if you were ever involved in doing that. As for orthotropic stuff you've described I hope you will find some useful information But I know how difficult it is to do so! Hello Lukasz. Wonderful blog! I am very happy that I found it today through your Linkedin profile.
Some people would say it is too late for me now. I agree to disagree. I have friend who already went down this path and now he is successful in FEA as well. I will dig out your blog to learn more. Thank you :. I think it's never too late to learn!
I wish you all the best on this journey. I really hope that you will find a ton of useful stuff here, also never hesitate to contact me if you will encounter any trouble! Hey Lukasz! The understanding obtained from this blog have made me feel or rather remembers the level of mastery I had in A level Physics,Chemistry and Mas my score was at 96 percentile,that's 10 yes ago. I do what I can, let's leave it at that.
I really appreciate you being here and reading what I wrote - that is certain. It's nice to know there are people around who enjoy my work : All the best. I think the trick is to divorce numerical methods from application fields. At my university we where taught all the methods before we used them for they are traditionally "best" at.
If you have complex 3D geometry and advection then use FVM but it is only 2nd-order accurate. If you need maximum accuracy and you have advection then use FD but you must simplify the geometry and perform a conformal mapping the an equi-spaced grid. If you have complex geometry and diffusion equations then use FVM but if you also have geometrical and closure non-linearity then use FEM.
Interestingly there are some structural problems where FVM is best - large deformations are easily handled by FVM practically a hybridization if FVM and FEM - AutoDYN for instance uses FVM , amongst others, which results in the so-called hydrocode solvers for material response to impact and detonation where the characteristic velocity of the "load application" us on the order or in excess of the acoustic velocity of the material.
Awesome stuff It looks to me like something requiring a pretty nice experience to be good at Seems you've so;ved the issue with browser refreshing :D. By "something" I meant- "well, this aerodynamic drag looks like someone with good CFD skills should have a closer look" :. I think, that "some" CFD can be useful for FEA engineer , for estimating ie wind forces or something like that order of magnitude, not the precise effects.
Better to know "something" than nothing at all :. For FEA, I'll keep an eye on Calculix solver, as they are now implementing Riks algorithms into it, and it has same input file format as abaqus ;. Well, it's always better to know something rather than nothing for sure.
I'm not sure however if I would trust my "something" enough to use the insights in an actual design :. I will have to look into Calculix for sure Thanks for dropping by I have no clue how did you find this article so fast BTW I haven't announced it yet :P. To design stuff with FEA you will need engineering design skills.
But what are those skiils, and what else will you need? Let's check! There is nothing wrong with using Linear FEA!
The trouble starts when you use it, unaware of the problems associated with this approach. With FEA you can model and analyze everything — solving an otherwise unsolvable problem. Without a doubt, linear FEA is the most commonly used tool in this regard. Design by lucasliszka. Back Academy. No worries, it will be clear in a second!
In the beginning, there was a differential equation! Share this post with your Friends! Facebook LinkedIn. Categories: FEA Fundamentals. Read more. I agree to receive marketing materials. Read more I understand that content sent to me will be adjusted to my needs based on what I do on Enterfea.
Unsubscribe anytime. CFD can be applied to structural problems and FEA can be applied to fluid flows, though the results in each case may be less accurate.
As such, the situations mentioned above are how these predictive processes are most commonly applied to ensure the utmost accuracy in advance of physical production. FEA gives our designers the capability to look into the future and gauge the viability of designs before we spend time and money creating physical prototypes. Every project we have run with FEA has been successful on the first try.
