Questions about the coordinate system for element stress

Altair Forum User

Dear all experts, I have two questions about the coordinate system in post-processing and pre-processing,hope you can help me:

1. In hyperview, what's the analysis system? Isn't it the same as element stress. please see figure 1 attached.

2. In hypermesh, when we create response for static stress, which coordinate system are the normal x,y and shear xy  in?  I guess the answer is the analysis system above,but I'm not sure.please see figure 2 attached.

I think the answers to these two questions are  very helpful for us to understand OS.Thanks!

HI,

 

The analysis coordinate system for an element reflects the system in which the results were defined for that element.  Therefore, different elements in a model can have different systems, depending on the way they were defined in the results file.  For example, a shell element can be in terms of its elemental system whereas a solid element could be in terms of the global system.

 

The responses are in global system.
