Hi Mike, 

Thank you for your reply. I've recently completed a code to calculate strain over the last week. When dealing with a single element or simple model geometries (such as a Ring or a basic cube), the strain results match very well with those from MATLAB. However, as the complexity of the geometry increases, the error in strain at each node becomes larger. To investigate the potential issue, I checked the integration points of each element. The Y and Z direction coordinates match well regardless of the geometry, but there are significant discrepancies in the X direction coordinates for some elements as the geometry becomes more complex (with some points showing up to a 10000% difference).

Model 1

 

Model 2

Model 3

 

It seems link you've provided do not contain an explanation for this aspect.

Is there an option within ANSYS to adjust the location of Gauss points based on the geometry? Why would the error be more pronounced in the X direction?
