Reply To: How can I calculate strain at integration point?

I have applied the same code to all models. My question is not about the code but rather whether, within ANSYS, the location of Gauss points changes for more complex geometries ( results match well for simple models regardless of the number of nodes and elements, I believe there is no issue with the code). 

There are discrepancy at both Gauss point locations and strain values. The Gauss points are derived using shape functions, and the strain-displacement matrix B, which is used to calculate strain, is obtained by differentiating these shape functions. Therefore, I suspect that the primary source of discrepancy lies in the Gauss point locations. 

Is there an option within ANSYS to disable such automatic adjustments to the Gauss point positions or shape functions? Or, if you have any insights or suggestions on how to address this issue, I would greatly appreciate your advice.
