insert body id into a postscript

[folle76]

Hello, everyone! I have this script working to table in a .txt item number, stress and coordinates.
How do I insert a new column with body id since it is a simulation of a set?
Thank you very much.

try using the component command

 

[stefano.garbin]

I assume you're working with classic ansys (mapdl).

I think of a somewhat complex and extremely inefficient way that allows you to do this
!cycle for a million times until, starting from an element, select all the knots and elements of a body
*do,i,1,1000000
Nodes attached to the elements
esln!select the elements attached to the knots
*end
Ksln!select keypoints attached to knots
lslk!select lines attached to keypoints
asll!select areas attached to lines
vsla!select volumes attached to areastry to imagine these clicks for each element of your table. . It's suicide! !

as it suggests volaff take your model in hand, and for each volume do (involume is the volume number,component name is the unique name cheques to the elements associated with a single volume):
vsel,s,,nvolume
allsel,below,volu
cm,nomecomponente,elemthen in postprocessing phase change your code accordingly

hi stefano, unfortunately I do not have the appropriate knowledge to implement your solution. I use the workbench and the script that I copied-paste over is practically yours. You generated it for me about two years ago.
Could you tell me a little?

vsel,s, involume (What should I put in place of nvolume? )Allsel,below,volu
cm,component name (What do I have to put in place as a component name? )♪

[volaff]

nvolume enter the name of the colume

ncomp the component name

 

[folle76]

I'm sorry to bother you until I'm exhausted. . .
but by component name can I put sch-3906-rrr, but by nvolume?
thanks to all

 

[volaff]

the volume number you want.

 

[folle76]

the problem is that I do not understand the difference between component and volume. I'm the same in my mind...

 

[volaff]

Do you know that all volumes of your fem model have at least one number?

 

[folle76]

Of course not. otherwise I would have already figured out what to put. the script runs without errors by inserting aleatori numbers for the volume but gives the result for all the elements of the axieme, does not return the result only for the elements of the component.

 

[volaff]

take a look at the guide before it is better.

Hello crowd76

I see you are working in workbench, so the situation from a certain point of view simplifies.
you need to work on groups of elements subdivided body by body. . .
then, on the tree on the left, in geometry, for each body of your set click with the right mouse button and add a "command snippet".in the snippet command go to write what is indicated in the figure.

Why this thing? workbench works with a "geometric ring" different from that of classic ansys, then goes to meshare the bodies with a meshatore different from classic ansys, but when it has to launch the simulations the underlying "motor" is always the same.
This "motor" however only sees groups of knots and elements, but not lines, areas and volumes.

the snippet command that you will insert on each body will go to create a "component", that is a set of elements for each body. is more or less equivalent to:

vsel,s, involume
Allsel,below,volu
cm,component name ,elem

in our case you will have a series of components called "component1", " component2" etc...

these components will then be visible to the other script you entered in the postprocessing phase.

I hope I've been clear enough, now you have to try!!!

 

[folle76]

Thanks stefano. Unfortunately I miss the final step. while I know the vba I have to say that I find this language ostico, even if I have not compulsed the guide to the bottom.
from what I understood in the postscript I can find a column with the name of the component I created in the prescript.
then select all the elements again and create an additional column with the component name, but how? Thanks again and good we!!
