Write stress values at integration points in punch file
Altair Employee Hey Guys,
I am comparing different post-processing softwares and their stress evaluation. For this I want to see the stress at the integration or gauss points of my calculation. I want to write those values in a punch file.
I use the following output commands in a linear static analysis:
The results in my punch file look this for one element:
As I understand, I can write the values like this:
<?xml version="1.0" encoding="UTF-8"?>
So there are no values for the integration points in my punch file.
What do I have to change in my output commands to have the integration point values written in the punch file?

From which solver the second output you posted is from?
Looks like the format is different but the values are the same in both the outputs.

The second output is the same as the first one. I have just changed the way it is written by hand, so I can understand the results better. Both are a punch output of optistruct of the same run.
I have also tried to write the gauss points values to an op2 and a h3d file but this failed too, only centroid stress was available.

Here are my model, and my output files if they can help you.
It is a quite simple model: It is just a rectangle with a force on one edge and constraints on all corners.

I can see that the results are different compared to h3d. I am going to this with experts.

I have called the german support last week and they said, that it is not possible at the moment to write stress at Gauss points to the punch file
I will now try to use OP2 or H3D and use a script to extract the stress at Gauss points
Thank you for your efforts
