Can't read the creep strain from result file

[andreasMANdeg]

hi,

i'm trying to read different strain types from my ANSYS result file with the helpf of the ansys-dpf-core package. This works fine for the elastic and plastic strain. But when using the same command -- model.results.creep_strain() -- for the creep strain, I get the following error message:

AttributeError: 'Results2462051095944' object has no attribute 'creep_strain'

In the attached picture you can see the available results for my simulation.

Thanks and look forward to your reply

Hi @andreasMANdeg Please post this on the DPF-Core Github page:
https://github.com/pyansys/pydpf-core

Also, see the DPF-Post document page and search for the term creep-strain...there is no result "creep_strain()":
https://dpfdocs.pyansys.com/search.html?q=creep+strain

The results are a bit more descriptive...like "nodal_averaged_creep_strains" etc.

Hi @andreasMANdeg, I've reproduced the error and will get back to you as soon as I have something.

I tested it from VM133 and indeed, the "creep_strain" result is shown as available.

However DPF does not have such operator. The error I get now is a little different.

The available result operators related to creep strain are:

So the issue is still valid (it should not be displayed in the print).

This is also an enhancement request to properly support it. It was discussed by email (April to July 2024).
Ricardo just had a look in the dev code. It looks like there is a prototype for the creep_strain operator, but it was not exposed because it does not work properly. If we want to expose it, more work is needed.
