Modelling a mechanical element in ANSYS

Click For Summary

Discussion Overview

The discussion centers around modeling a mechanical element in ANSYS, specifically focusing on obtaining total reaction forces at the supports rather than individual reaction forces at nodes. The scope includes technical explanations and potential methods for data extraction within the ANSYS environment.

Discussion Character

  • Technical explanation, Exploratory, Debate/contested

Main Points Raised

  • One participant seeks to find the total (resultant) reaction forces at the supports instead of the individual reactions at the boundary nodes provided by ANSYS.
  • Another participant suggests using a post-processing script to achieve the desired results, indicating that it can be laborious but possible.
  • A different participant inquires about the specific element type being used, implying that this may affect the approach to obtaining the total reactions.
  • One participant mentions the use of etable and post-processing calculator operations as potential methods for extracting the necessary data.
  • There is a suggestion to script the extraction and perform integration in a macro, which might simplify the process compared to exporting data.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the best method to obtain total reaction forces, and multiple approaches are being discussed without resolution.

Contextual Notes

Limitations include the potential complexity of scripting and the dependence on the specific element type used in the modeling process, which may influence the methods available for data extraction.

I have modelling a mechanical element in ANSYS. Those who have used it will know what I am talking about. I want to obtain the reaction forces at the supports (Fx,Fy,Fz,Mx,My,Mz). So I go to List Reaction forces command window and Ansys gives me a list of nodes and its single reaction:

PRINT REACTION SOLUTIONS PER NODE

***** POST1 TOTAL REACTION SOLUTION LISTING *****

LOAD STEP= 1 SUBSTEP= 1
TIME= 1.0000 LOAD CASE= 0

THE FOLLOWING X,Y,Z SOLUTIONS ARE IN GLOBAL COORDINATES

NODE FX FY FZ MX MY MZ
1424 0.44869E-01 0.66813E-02 0.78517E-01-0.49352E-01 0.20655E-03 0.20254E-03
1425 0.83405 0.73892 2.3231 -5.4600 -0.54559E-03-0.28838
1426 -0.57409E-01 0.76036E-02 0.10521 -0.58399E-01-0.15650E-06 0.33950E-02
...(more)

Something like that. I suppose that all these nodes are the nodes at the boundaries, which are for instance, each of the four supports of the element.

My question is: Is there anyway to obtain the TOTAL (RESULTANT) reaction in each support, instead of the single reaction in the nodes coincident with the boundaries?.

Thanks.

This is not a reply to your question, but I wondering if you know any web sresources for ANSYS, like ANSYS tutorials or e-books etc

Thanks
 
Sorry, I don't. I used the tutorial which goes inside the Ansys software.
 
"ANY" - within a post processing script at least (can do pretty much anything, but can be laborious), I'll check the post processor manual how it goes, can't remember from the top of my head, what particular element type you're using?
 
You tried etable & the post-processing calculator operations? I'd script the extraction & do the integration in a macro but if could get it done there or without exporting the data otherwise would be easier.
