difference between element solution and element table.

[lo85]

Hi, guys. I wanted to ask something.
what are the correct result values in terms of stresses that returns ansys?
I noticed that there is a difference between the values returned by the two procedures

plot result-->element solution-->structural force-->x component of force

and those defined by etables as :

define etable-->add--»nodal force data-->fx

What are the right ones to use for projects example of a generic plate that I need for example the stinging moment mx or any other stress?
Thank you.

to better understand what the etable is for.

Hello, thank you for the answer, but I had already seen that file, without solving my problem,
the fact is that with the two procedures I get two different results, I wanted to understand why and what are the right ones.
what do you usually use?

But they're both right!

If you want to plot the diagram of the bending moment you must use the etable that gives you the value of the maximum and minimum voltages of the nodes to which the element refers.

Perhaps I am understanding, is it possible that one refers to the values to the individual knots that make up the ith element of the mesh and the other instead takes the mediated value of the individual 4 or 8 knots that make up the single element?
I'm sorry for the insistence, but I'm at first sight and I'd like to understand how to proceed.
thanks anyway to patience

more or less you have centered the concept.

Good evening

Sorry, one last thing, just to have another opinion. for any verification. What values do you take? ? ?
Do you take into account the size of the mesh or are values already created on the measuring unit? Thank you.
