Output question

[ssn3]

I have a small question on outputs such as E11,E22,E33,S11,S22,S33,U1,U2,U3 etc. Lets say I have use an orthotropic material and have defined the different material orientations. The outputs I mentioned earlier, are they based on the global coordinate system or the local coordinate system that I used to define the material orientation? Is there a way to get the outputs based on global and local at the same time? These are the questions that I would really need an answer too. Hope someone could help me with this. Thanks in advance.

are they based on the global coordinate system

Yes.

Is there a way to get the outputs based on global and local at the same time?

Search "local coordinate system" in the CAE User's Manual. CAE lets you carry out the transformation.

I created a simple model to test this out. Using a orthotropic material I kept changing the orientation of the material. Based on this simple test I am pretty sure it gave results for E11,E22 and E33 based on the local material orientation. I used unique nodal position to get the output values. Not sure if I am doing it right.

Read the section entitled "Direction definitions for element variables" in the Analysis User's Manual (4.2.1; v6.11).
