copiare solo mesh

[volaff]

Hello everyone, I would have the following problem.

the area in red (although not seen) is meshata while the other small rectangular areas (1 2 3 4) are not.

I have the need to copy the mesh of the area in red on areas 1 2 3 4 (green).

between the area copy options only appears area or area + mesh.
in fact areas 1 2 3 4 already exist and go only meshate.

to use the copy area command I have to delete them and then use it or should I make a mesh area by area equal to the one made in the case of the area in red?

Good day to all.

perhaps the command copy only mesh does not exist!!!

 

[stefano.garbin]

the command exists and is called egen.
But I apologize if I allow myself but I perceive a sort of confusion and lack of strategy in addressing the problem.
rereading your posts seems to me to understand that you have to somehow shape a kind of panel, perhaps with reinforcement longheroni, all fixed through rivets.
Am I wrong?
the model you inherited from someone else, and maybe it was done a few years ago with modeling criteria that today perhaps are no longer "optimal".
you have tried to operate on this model by modifying it but you have found yourself faced with great difficulties (hardpoints etc.)
Have you ever thought of "going from scratch" and building your modeling strategy looking at the problem with a more general vision?

Hello stefano thank you very much for the answer.
then what you wrote is totally correct except the last thing.
Now I'll explain.
I would have wanted to remodel the panel with longheroni, frames ect ect but my prof told me: "do not take initiatives of his will", so he told me that I have to milegate the model by correcting the position of hardpoints (and, consequently, that of rivets).
the difficulties I have encountered have not been few (and, perhaps, will not be) you want for my lack in using ansys you want for the complexity of the intrinsic problem.
It's like, four years old, I was already given a motorcycle in my hand without me being able to drive the bike.
That's why, sometimes, I'm completely dismissed.
the prof, for any eventuality, I always contact him by email because, in fact, I use from 5/6 hours between going back to university (I live in another province) and go to ask for a thing of 5/10 minutes, sometimes, I do not think it is exactly the case.

I'm sorry the "sfogo" but it kind of took us! !
Thank you again!

Nothing forbids you to do this on your own and then submit your results.

 

[volaff]

That's true, too.
Do you have suggestions on how to build the model differently and more "simple"?? ? ? ? ? ? ?
It's a shame not to have the 3d file of the panel.

cmq I would at least end up with what he told me to do and, if I have time, do something on my own.
on the "do not take initiatives" seemed very categorical to say the truth!

 

[stefano.garbin]

Do you have ansys database with the right geometry?

 

[volaff]

in fact I have a model "only geometry" where there is the panel plus hardpoints (some of these hardpoints is wrong but I corrected it)

 

[volaff]

having the model with geometry and hardpoints how could I do the same job but differently? ! ?
In fact, hardpoints were created to be able to carry out the rivets by beam4 and to be able to detect the deformations of the model.

greetings

 

[stefano.garbin]

the strategy could be to avoid the use of hard-points by correctly dissecting geometry in such a way that, at the hard points, there are normal keypoints deriving from lines that cross.
some questions:
Are the various parts of your model connected only through rivets?
are there contacts between panels (among them) and between panels and longherons?
Is your analysis a simple structural or how to vibrate (modal analysis) or vibration (psd excitation) come into play?

 

[volaff]

thank you for the questions but above all thanks to your answer.
I will try to be shorter and more precise than I can.
first of all I explain why I use hardpoints: they have been used (placed) in correspondence not only of the ends of the rivets but also in correspondence of the strain gauges used to test their deformations.

the two main panels are connected (and overlapped partially) through rivets used not only to connect the skins but also to connect the longherons vertically with other elements called shear cleats.

My analysis must only be structural (under 25,000 kp load) and then if possible it will pass to a dynamic analysis.

if you want (and time) I have attached the pdf file to make you better understand how the panel is made

Thank you very much for your availability.

 

[stefano.garbin]

seems very interesting to a first look.
When I have a little free time I read everything, because there is always to learn, even for my field of work.

 

[volaff]

that is a chapter of the graduation thesis that I must "continue"... there are four more

the problem is that I, on the one hand, would like to do something of mine perhaps starting only from the geometry that I already have but I do not think I have all the tools already available; On the other hand I would not like to go against my teacher who told me not to take initiatives.
What a dilemma!

in fact I would like to see what happens by making changes to the hardpoints I have made, regenerating mesh and elements of the "errate" parts.

 

[volaff]

returning to the "original" speech how can I copy a mesh of an area on another area? ?

I try to explain myself with an example.
we imagine having a cross-shaped element (a horizontal plate and a vertical perpendicular); in making mesh I have the need that the knots of a plate (e.g. the horizontal) coincide with the knots of the vertical plate and everything there to ensure congruence in deformation.
How could I think of operating?

Thank you so much and good day to all!

The debate can be closed.
Have a good day! !
