Strange principal stress in postprocessing

Post by vpapanik »

Hello ! I have found a strange result in postprocessing, specifically the principal stress calculation.

Here's my result table :

and here is a cross check using two different online calculators :

3.png
3.png (192.41 KiB) Viewed 6222 times
The tensile principal stress from GiD is 4801.2 and from both online calculators is 3209.7.
In my model, the checked element has not actually cracked which means that the principal stress should be lower than 4400.0. With the GiD result it should be cracked, but I think that 3209.7 is actually right.

I can't figure out what is happening so I would really appreciate any help.

I think that this is a bug that I have detected and fixed for next 14.1.9d version,
but this version is not already publicly available for download, it will be soon...

Thanks a lot, looking forward. For the time being, I made custom principal stress results in .post.res.
