first steps with the method of finished elements

[mir]

Hi.
I press that I never used fem or surroundings for load analysis. I just wanted to ask if it is complicated to do analysis of welded flanges subjected to stinging and torque moment without having to know in depth the program and if you have any program to recommend me.

Thank you.

in my opinion yes....
the problem is that without some experience or preparation (courses, etc) it is quite difficult to understand whether the results of the analysis are true or not, as the software will never give you this indication. to me it has happened, for example, doing tests, to get extremely different results by gradually changing the conditions of the problem (more or less dense, tetrahedral or hexaedric elements, etc.).

depends also on the type of precision you look for: If you agree to understand the order of magnitude of tensions, i.e. if for you it's okay to know that the sigma at that point is between 10 and 100, but it's definitely not 1 or 1000, or if you need a high precision, maybe around +/- 5%.

Hi, mir,

each fea produces a huge amount of racked numbers in files, from which it produces graphics and images with beautiful colors.

from this you must begin to understand if the numbers are right and if yes, how to interpret the results and how to exploit them for your things.

If you want to do this, without having to know in depth the program, you should develop fea interfaces on the things you need, or given the cad, and wanting to simulate a certain thing (e.g. welding, with such welding machine, wanting to see which is the final form tensioned according to the cooling you have), you generate the results (e.g. the image or the report, or the range of the most distorted points).

on the subject I'm usually saying that the fem software is for the engineer what the calculator is for the accountant...and I with the calculator can't make the accountant!
