how to get and save in an external text file the maximum nodal displacements in y direction for a volume
Hi,
I am doing a static analysis to a volume. How can I get and save in an external text file the maximum nodal displacements in y direction for the volume ID 1 and 2?
Best regards,

Hi Hugo,
I think ANSYS can provide displacements for nodes not volumes, as I
remember.
If I understand your post correctly, You can select your volumes 1 and 2
using VSEL then use NSLV to select the nodes associated with such vols.
Then using *GET you might be able to extract the y-displacements. To export
to a file, try *VWRITE.
This is a very basic procedure. Maybe someone else could provide a more
sophisticated method.
Good luck!
Mohammad

this is the code I'd use in APDL following the simplistic method that
Mohammad suggested
Crate a ELEMENT component for the elements in the specific volumes:
vsel,s,,,volid1 !replace volid1 with the number of your volume
eslv, s, 1
cm, CMVOL1, elem
vsel,s,,,volid2 !replace volid1 with the number of your volume
eslv, s, 1
cm, CMVOL2, elem
!assuming you are already under /post1
*cfopen, outputdata, txt
*vwrite
component,DYMax
*do, i, 1, 2, 1
cmsel, s, cmvol%i%
nsle
*get, nmax, node,,num, max
*vget, nmasm, node,,nsel
*vmask, nmask
*vget, disp_y, node,,u, y
*vmask, nmask
*vscfun, dymax, MAX, disp_y
*vwrite, i,dymax
CMVOL%i, %f
*enddo
*cfclose
Other approaches can be followed:
- APDL: in the *do loop just plot the UY figure and *GET the maximum value
of the current displayed plot
2)Python scripting in Ansys Mechanical

Unless I mis-remember, this was aways a pretty trivial problem. Once you issued NSLV you can just list the displacements to a text file; then open a spreadsheet program and import the text listing. You'll have columns with al 6 displacements and it's simple to delete the columns you don't want. In the text file you can also format the numerical format of each column for the type of notation and rounding format you prefer. Arithmetic rounding and text formatting in Excel or whatever spreadsheet you like is always easier that fiddling around with the ANSYS numerical formats, and you can export Excel to your report writing software or do sorting and math operations much easier and better than with ANSYS. If someone handed me an ANSYS listing when I asked for summary results, I tended to be grumpy and dismissive and no fun at all.
