Getting Started with ANSYS APDL: Resources for Beginners

Click For Summary

Discussion Overview

The discussion centers around getting started with ANSYS APDL, focusing on resources for beginners, coding extraction from models, and specific modeling queries related to stress and strain analysis. Participants seek guidance on various aspects of using ANSYS APDL, including interfacing with MATLAB, defining elements, and troubleshooting errors in modeling.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • Some participants request basic resources or books to learn ANSYS APDL.
  • Several users inquire about extracting APDL code from existing models in ANSYS.
  • Participants discuss methods to obtain stress and strain data for an 8-layer shell beam model, with suggestions on using post-processing options.
  • One participant mentions the challenge of filtering stress data to find maximum and minimum stresses and deflection, with a suggestion to use MATLAB for data processing in ANSYS Classic.
  • A user seeks clarification on how to interface ANSYS with MATLAB for running simulations.
  • Another participant asks about defining a gravity spring in the fluid80 element and whether it is a default feature.
  • A user describes difficulties in obtaining a stress-strain curve for a woven fabric model due to errors related to scratch space and requests suggestions for resolving the issue.
  • One participant notes the absence of a "design opt" feature in ANSYS APDL 15 compared to version 12 and seeks advice on applying design optimization in the newer version.

Areas of Agreement / Disagreement

The discussion contains multiple competing views and unresolved questions regarding specific modeling techniques and troubleshooting methods. No consensus is reached on the best approaches for the various issues raised.

Contextual Notes

Participants express uncertainty about the specific steps required for interfacing with MATLAB and the implications of version changes in ANSYS APDL. There are also mentions of limitations related to scratch space in modeling, which remain unresolved.

i am new to the APDL in ansys and i need some basic books or sites to learn APDL
 
Physics news on Phys.org
I have modeled in ansys now i want it's apdl coding from that model.how can i get it?

open Ansys, file -> List -> Log File
 
i have modeled 8 layer shell beam. in ansys i want stress and strain in each ply, how will i get it.

after the solution is done, select "General Postproc->plot result->contour plot" to see the cloud pictures or select "General Postproc->list result->Nodal Solution (or Element Solution)" to see the data.
 
i have modeled 8 layer shell beam. in ansys i want stress and strain in each ply, how will i get it.
"General Postproc->list result->Nodal Solution (or Element Solution)" with this i am getting thousands of element stresses
But i want only SMX(maximum stress), SMN(min.stress),deflection on 8 layer.
how to get that?

OK, if you are using Ansys Workbench, the SMX and SMN are automatically listed. While in Ansys Classic, u can use Matlab to deal with the data to find the SMX and SMN

1)HOW? i.e please tell me the step how model deal with MATLAB?
 
i want to run ANSYS using matlab.
so how intrface these?
please.tell me

gravity spring in ansys

Dear friends,
how can define gravity spring in fluid80(ansys)? or that is a default in this element?
regards

Dear friends.
I have created a model (woven fabric) for my projects and include in matrix box in order to get the stress strain curve. Unfortunately I can’t get it and errors keep on occur (this model requires more scratch space than currently available). I have already done the element type, Boolean operation (glue) between woven fabric and matrix box, material properties and element meshing. I am doing structure analysis on my model. Kindly could anyone please give me any suggestion for this problem? Thank you in advance.
Regards.

HI,
i was using ANSYS APDL 12 and there was a "design opt" in the main menu tree to the left. it s for design optimization. however now i built my model in ansys apdl 15 but there s no longer "design opt" in it. any ideas how to apply design optimization in apdl 15??
thanks
