Getting different 1st principal stress results with apdl script and workbench
Getting different 1st principal stress results with apdl script and workbench
(OP)
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:
both results are sampled at the last timestep. The results are:
Thanks in advance
Best regards BTHS

CODE --> apdl
*get, HS_10, node, HS_nodenum2, s, 1
- 0,99784 for the GET method
- 0,99873 for the probe method
Thanks in advance

Thank you for your input! I just checked, they both output the same 3.3986e-002. Using the following command:
CODE --> apdl
and the "Total deformation" on the vertex at the same node.

*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,
