Okay, thank you.

only one question: when I open the model already is beautiful meshato and loaded!

Once I wrote the text fiel, do I have to upload it from "read inmout from" and select it? ? ?

Thank you so much!! !

as my fixed pc has only 2 gb of ram and the only model is about 1.80 gb, I have to load it on the laptop (which I did on purpose).

See you soon!
 
I get out of this by loading through "read input form file":

"missing separator between two fields"

I also tried to eliminate "comments" but always comes out the same mistake!!

Have a good lunch!
 
Let's make some clarity.
So you open up and find yourself a meshato model?
Do you have to keep mesh or can you regenerate it?
In case you have to keep mesh the strategy changes a little...

as for the command file try to do so:
copy-paste one line at a time in the command area of ansys and see which line generates error (it is certainly an error in the syntax of some command).
 
then it is not a problem to regenerate mesh: I care that deformations fall into a % change of + 10% - 10% compared to experimental data.

Now I try to glue one line at a time and see what happens.
Thank you once again!
 
I realized that in the file you had psotato there was a missing one! Now the rivets in the central zone I cameo plotted without problems... The plotted rivets are perfect aligned. . .
with the same methyladia I have to understand which rivets are wrong then.

thank you stefano too genitle,

Now I also see what the prof says.

See you soon!
 
Well, then the new rivets created seem correctly aligned.
So what do you want to do?
 
That was the problem. I'll explain.

the prof told me, practically, that the rivets in the central area went "raddrized" and I was a bit surprised to see them straight.
because the panel is riveted even along the orthogonal direction to that of the plotted rivets thanks to you (in more areas) I asked the prof if I have to work on these rivets.

Obviously I will go to plot them a bit at a time having the text files "original" and modifying them as done thanks to your help.

As soon as I have his news, I'm going to work.

I can only say thank you very much.
Have a good night!
See you soon!
fly
 
I've just been told to fix all the riots.

from tomorrow I modify all the text files and control which are the rivets charged to edit!

See you soon! !

Thanks again for everything!
 
hi, finally I am resurrected to plot (thank you stefano) all beam, but all!! !

I have visually checked what were wrong or not and the result is reported in the annex.

once "loaded" the "modified" file if I go to type klist to know the location of the various keypoints to video only two keypoints (idem for knots).

I visually have the image in the attachment (image 1) while from the keypoints point of view I only have two.

What's wrong?

thanks to all and good day! !
 

Attachments

There's nothing wrong.
probably the routine that selects beam4 is finished with only 2 selected keypoints.
if you want to select all keypoints write
Code: 
xsel, below
if you want to select the keypoints attached to the rivets write
Code: 
nsle,s!select the knots attached to the active elements
ksln,s!select the keypoints attached to the above selected nodes
 
Now I can plot the knots about the twisted rivets. the problem is that if I want to understand which end bnodes are by making plotctrls----numbering----activating node numbers and the option "colors&numbers" the numbers are overlapped and, in fact, unreadable.

if I don't erro there's no command that lets me select the nodes by mouse?? ? ?

so knowing the ends knots I could go to change the rivet by erasing the wrong one and, by putting, the "new", at least I think!! !

Have a good day!
 
eh si caspita, ti selezioni i nodi con il mouse! otherwise with the casino of rivets you become crazy! from the menu "select" select "entities". opens a window, make sure to select "nodes" - "by num-pick" - "reselect".
 
More crazy than I am is difficult..ah ah... thank you very much... .
ps: if you have to change only a few rivets it is possible to create a text file in which I delete the "not good" rivets and put those "rights" or you have to leave and change the original text file?
 
Hi, I'm back here breaking the...

I have a small problem.... when vqado selects the incriminated keypoints (or knots) appears in the written "there are 8 keypoints at this location": Now how do I know if the keypoints is the right one? ? ?

I think I just have to plot one at a time and try that, don't I?

Click to expand...
ps: as the wrong rivets are however few I should create them by hand, instead of doing countercyclical cycles.

In fact, I have to eliminate the riddles and replace them with those I have the cohort.

I was wondering what was the most correct procedure to follow.
every suggestion is well accepted!

Have a good day!
 
From the flyers you start having your legs to walk with ansys!
make a backup copy of your job and do some evidence!
ask confirmation at every step you do is not a good thing!
 
Thank you very much! !

only confirms that I can delete rivets and create new known coordinate medainte, that's all!

See you soon!
