maximum stress on macroelements of a model

[lo85]

Hey, guys, excuse the banal question.
If I have a structure made up of different parts, how can I detect maximum stress on each macro element in order to be able to audit each one?
I'll explain better.
if I do an analysis with ansys on a structure, example in masonry, consisting of shell elements that in turn are meshati in other triangular or square elements of size for example of 40cm, how do you define the stresses you should take for each panel to check?
each panel consists of a hundred triangular elements and my values are on those. then you have a total maximum, but of the entire building. but I have to do a verification on the individual blocks or on the individual male walls.
the question is very generic, it is as if I have 4 floors and I want maximum stress on the individual plans but the program returns me the maximum on the whole model.
Is there a way to define for example an area of which I get its maximum stress or deformation by ignoring the rest of the model?
Thank you.

I understand you're using ansys classic.

do you have a real constants, material or similar assignment?
I better explain each "pannello" has different characteristics from others in terms of material, real constants, ect ect? ?

 

[lo85]

are shell281,(use version 14), features are set by sections. I have 10 shell sections where there is thickness and material. the shell element 281 does not require realcostant (even if I had seen a boy who assigned the shell281 beam188 realcostant so he could give it thickness and maternal, but he could not read the tensions in the final stage).

 

[volaff]

therefore each plane is formed by shell defined by right section? !
in practice you have not assigned any real constants to the shell but given thickness and material by shell section right? ? ?

 

[lo85]

yes, also because it does not make me define a realcostant for these shell281

 

[volaff]

try using the command:

esel,s,sec,,num_section type:

esel,s,sec,,2

so select all shell281 elements having as sect number 2.

once you do this plot the tensions you want.

 

[lo85]

I think it's him, can I turn this command so that you show me a certain area? example area 4?

 

[volaff]

Yes, but let's see if you get there alone... if I tell you everything now... alone you will do nothing

 

[lo85]

thank you, but I have already tried, I have seen the esel command, but I think I have understood that not from the possibility to select an area in particular.
no I know if you have another command in mind, I have seen this and in the meantime I say thank you because it is already a good thing.

 

[lo85]

Nothing I can't do

 

[volaff]

the commands you need you find them googlando a little...... if you do not want to look for even a little!!!

uses the help that doesn't hurt.
I also learned what little I know, so!

 

[lo85]

No, I did it. Thanks. .

 

[volaff]

purpose of the forum is to share the solution when you got it

 

[lo85]

You're right.
However there is a big button like a house on the main bar, select , and I hadn't seen it.
it opens and you play a bit with that.ti allows you to select and isolate any line, point, and also areas.
