Getting different 1st principal stress results with apdl script and workbench

[BTHS]

Hi

I have a simulation where i use a *get command to extract stress from a specific node. When i check my result with the "Maximum Principal Stress" using a stress probe option in the vertex at the node, i am getting a different result. the GET command used is:

*get, HS_10, node, HS_nodenum2, s, 1

both results are sampled at the last timestep. The results are:
[ul]
[li]0,99784 for the GET method[/li]
[li]0,99873 for the probe method[/li]
[/ul]

Why is that? Are they calculated using slightly different methods or something?

Thanks in advance
Best regards BTHS

Hi L_K

Thank you for your input! I just checked, they both output the same 3.3986e-002. Using the following command:

*get, my_04, node, HS_nodenum1, U, sum

and the "Total deformation" on the vertex at the same node.

Hi BTHS,

*GET command retrieves averaged nodal results based on selected elements. Were all elements selected before *GET?

The difference is small, could it be due to graphics algorithm?


Thanks,
