Hello everyone !
Someone can provide examples of finite element analysis calculations using 2D and 3D elements. If anyone has experiences with this type of calculation please help me.
Thanks !
Is it one 2D example of FEM&

Hi,
Mathcad has a e-book called "Finite Element Beginnings" by D. A. Pintur. This is an introduction you could use.

I Iramoslima,
the argument, as you know, is vast and complicated. I give you an outline about the difference method theory which is almost similar to the one on finite elemets method, to get an idea of what it is. I add some examples, of which some are downloaded from the community. I forgot to tell you that some results must be verified since they are not copied by some text.

It would be more correct to write so:

Hi,
do you have any questions?
Errata-corrige:
Hi,
when working with partial differential equations we can replace partial derivatives with finite differences approximations as previously seen. If we opt for finite element method, we must seek an approximation w to the unknown function like this:
where P(x) is a prescribed function (basis functions or trial functions or shape functions) and unknown coefficients u.
This has been a very interesting and informative thread. You have done a great deal of work. However, it is difficult to follow the content in the large images. Would you be willing to post the worksheets?
Answer to:
I'm sorry but it's not possible.
If you have support, look for article "CS173039" Finite Element Beginnings. I haven't gone through the course myself but it might be worth checking out.
