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.
Please check the following discussion: https://community.ptc.com/t5/PTC-Mathcad-Questions/Finite-Element-Analysis-where-to-in-Prime-Mathcad...
Mathcad has a e-book called "Finite Element Beginnings" by D. A. Pintur. This is an introduction you could use.
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.
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.
