Ansys workbench

[JarossR]

Good day,
I have used Ansys workbench mechanical to calculate the stresses. When I tried to export my results, I could only see the node number versus the stress value (see the example below).


Node Number Equivalent (von-Mises) Stress (Pa)
3015 5.1049e+007

How can I get the coordinates of node number 3015? I appreciate your help.

by looking at the model !
maybe you can see an echo of the model input in the output, and search for the node. Or maybe ask ANSYS "where is node 3015 ?" There should be a feature to display nodes.

but why ? These days we look at the stresses on the model. In the very olde days we used to have to leaf through reams of paper output, but today one look at a screen does most of it. if the node isn't visible, you should be able to have ANSYS point it out to you.

Have you opened the manual ??

Good day,
Thank you for your time & assistance. Let's open the manual.

2.26. Data Export​

Mechanical enables you to export specifically supported analysis data to one or more of the following file types. Review the following topics based upon the desired export file format.

19.17.6. Exporting Results​

To export the data of a contour result, right-click the desired result object, select Export, and specify a file name and type. Supported file types include Text (.txt) and Excel (.xls). Text format is the default file format. However, the application always creates and displays an Excel file even when you save the data in text format. The exported file includes headers that display the node ID or element ID, and the result name and unit. Note that the application may not sort the node/element ID column. A good question is, "Where is node 3015?" I used a trick and found it, as shown below. (ID 3015) 3.16E-02 5.83E-03 7.88E-02 (ID 3016) 3.04E-02 7.28E-03 7.88E-02 (ID 3017) 3.10E-02 8.31E-03 7.88E-02 (ID 3018) 3.12E-02 7.49E-03 7.88E-02 When I attempted to plot the stresses found in the .txt file, I obtained results that did not make sense. See the attachment, please. Looking forward to hearing from you. ​

I have just about no idea what you are doing !!??

what you found may be locations, but look to me to be deflections.

let's start at the beginning ...
I assume you didn't create this model ?
and have been given a model (?) and an output file ?
and tole "make sense of this" ??

 

[JarossR]

Good evening,

To address your concerns, I would need to make sure that I have created the model. Additionally, my results do not display the deflections.
Step 1: I select the "Selection Information option in the Tools group on the Home tab to obtain the coordinates of a node with ID 3015.

Step 2: As I mentioned earlier, to export the data of a contour result, right-click the desired result object, select Export, and specify a file name and file type.

So, I got the following.
(ID 3015) 3.16E-02 (x) 5.83E-03 7.88E-02 (z) 5.10E+07 (stress)

I have used Python to obtain the results for the other nodes.

As I said before, when I attempted to plot the stresses found in the .txt file, I obtained results that did not make sense. I'm looking forward to hearing from you and appreciate your help.

Thank you for your recommendation. Could you please send me the link to the ANSYS forum? I appreciate your help.

I was going to write something snitty, but then it is hard to find ! ... in Simulation under Engineering Computer Programs

 

[JarossR]

Thank you. I (myself) have already solved the puzzle of exporting results from ANSYS.

 

[rb1957]

ok, not much of a "puzzle" ... when you know how !

are you plotting on a deformed model ? the black part of the ANSYS plot looks 'odd"

are there reasons for the stress variations ? (like maybe applied loads)

 

[JarossR]

What is the black part that appears out of place?
Yes, the reason is that I used an intruder *gambling die* to measure granular surface tension.
Our recent study significantly enhances the field of granular mechanics by introducing a groundbreaking granular-media calorimeter, which plays a crucial role in understanding the thermodynamics of granular streams under horizontal vibrations. We made a remarkable discovery: at low peak accelerations relative to gravity (Γ), a submerged intruder resting on the free surface of a rotating granular sample defies Archimedes' principle. Instead, we uncovered an important resistance force called pseudo-surface tension, which not only deepens our theoretical understanding but also has practical implications for various industries that deal with granular materials. The issue of energy dissipation during low-velocity collisions between small grains has been a persistent challenge for researchers in the field of granular flow. To address this, we utilized cutting-edge molecular dynamics simulations to examine the relationship between the coefficient of restitution and impact velocity, with the goal of accurately modeling energy dissipation. Our findings reveal that aligning simulation results with empirical data from our calorimeter substantiates Love's assertion that small grains exhibit slightly inelastic behavior during very low-velocity impacts, providing an accurate estimation of pseudo-surface tension. This research enhances our understanding of granular materials and paves the way for future innovations in the field.

What do you think?
By the way, my name is Jaross. Nice to meet you.

Hi,​

rb1957, honey, are you OK?​
